It turns out that CB_TAG_ACPI_GNVS is handled in both x86 specific and
common coreboot table parsing code. The MRC cache case used only by
x86 is handled in the common code.
This patch restores sanity and moves processing to where it belongs.

BUG=none
TEST=verified that arm and x86 targets build.

There are three instances of coreboot.c in libpayload. for x86, arm
and arm64 architectures. The arm and arm64 instances are exactly the
same. The differences with the x86 instance are as follows:
- a very slightly different set of coreboot table tags is parsed (one
tag added and two removed)
- instead of checking a fixed address if it contains the coreboot
table, the x86 version iterates over two address ranges.
This patch refactors the module, leaving architecture specific
processing in arch subdirectories and moving the common code into
libc.

For memalign() requests the current allocator keeps metadata
about each chunk of aligned memory that copmrises the size
requested. For large allocations relative to the alignment
this can cause significant metadata overhead. Instead, consider
all memalign() requests whose size meets or exceeds 1KiB or
alignment that meets or exceeds 1KiB large requests.
These requests are handled specially to only allocate
the amount of memory required for the size and alignment
constraints by not allocating any metadata as the whole region
would be consumed by the request.

The serial driver hangs in cases when FIFO has more than single word to be
processed. Easiest way to reproduce is to paste a string of greater than 4
characters in cli.
Clearing the RXSTALE interrupt without draining all the characters from FIFO
leads to the issue as the driver is dependent on msm_boot_uart_dm_read
function to reinitialize for next transfer.
Logically the driver is organized in such a manner that next transfer never
gets initiated till rx_data_read < total_rx_data. Clearing the RXSTALE without
consideration of total number of characters (or words) unprocessed makes the
msm_boot_uart_dm_read to return on the first if conditional. Thus the driver is
stuck forever.
A quick fix is to avoid clearing the stale interrupt. Reset is handled whenever
a new transfer is initialized in msm_boot_uart_dm_init_rx_transfer.

Looks like we got our first SoC that actually insists on using
word-sized accesses for its MMIO registers with the Rk3288. This patch
changes the GDB command handler for reading and writing memory to always
perform word-sized accesses. This isn't really perfect since the remote
GDB interface is just not really meant to interact with MMIO (e.g. you
shouldn't use this on something with read side effects), but for most
of our purposes it should be good enough.

setbits_le32() is not really arch-specific... the arch-specific part of
accessing memory is wrapped by readl() and writel(), and the endianness
can be accounted for with the right macros. Generalize the definitions,
add a be32 version and move them to endian.h so that all platforms can
use them. Also include endian.h from libpayload.h so we won't update any
payload's old use of the macros (endianness is something useful enough
to always have avalable anyway, and shouldn't clash with other things).
This also fixes a bug where these macros would only be available if
libpayload-config.h had been independently included before.
Also fix a bug with readl() macros on all archs where they refused to
work on const pointers (which they should).

In cases where timer clock frequency is not an integer number of
megahertz, the calculations in timer_us() lack accuracy.
This patch modifies calculations to reduce the error. The maximum
interval this calculation would support decreases, but it still is in
excess of 1844674 seconds for a timer clocked by 10 MHz, which is more
than enough.

The current default memcpy first copies single bytes to align the
amount, then copies the rest as full words. In practice, the start of a
buffer is much more likely to be word-aligned then the end, and aligned
word access are usually more efficient. This patch reorders those
accesses to first copy as many full words as possible and then finish
the rest with byte accesses to optimize this common case.
This fixes a data abort when using USB on ARM without CONFIG_GPL. Due to
some limitations of how DMA memory is set up in coreboot on ARM, it
currently does not support unaligned accesses. (This could be fixed with
a more complicated patch, but it's usually not an issue... unless, of
course, your memcpy happens to be braindead).
Also add word-aligned accesses to memset and memcmp while I'm at it, and
make memcmp's return value standard's compliant.

This patch adds the ability to attach a GDB host through the UART to a
running payload. Libpayload implements a small stub that can parse and
respond to the GDB remote protocol and provide the required primitives
(reading/writing registers/memory, etc.) to allow GDB to control
execution.
The goal of this implementation is to be as small and uninvasive as
possible. It implements only the minimum amount of primitives required,
and relies on GDB's impressive workaround capabilities (such as
emulating breakpoints by temporarily replacing instructions) for the
more complicated features. This way, a relatively tiny amount of code on
the firmware side opens a vast range of capabilities to the user, not
just in debugging but also in remote-controlling the firmware to change
its behavior (e.g. through GDBs ability to modify variables and call
functions).
By default, a system with the REMOTEGDB Kconfig will only trap into GDB
when executing halt() (including the calls from die_if(), assert(), and
exception handlers). In addition, payloads can manually call gdb_enter()
if desired. It will print a final "Ready for GDB connection." on the
serial, detach the normal serial output driver and wait for the commands
that GDB starts sending on attach.
Based on original implementation by Gabe Black <gabeblack@chromium.org>.

(You can also SIGSTOP your terminal's parent shell and the terminal
itself, and SIGCONT them in reverse order after GDB exits. More
convenient wrapper tools to do all this automatically coming soon.)

There have been leaks of GPL code into libpayload for a while now, for
new features or improvements that require third party code with no
adequate alternative among BSD-licensed software. It seems silly and
counter-productive to keep holding back features and performance
improvements from libpayload for a use-case (proprietary payloads) that
doesn't even seem to be implemented anywhere to date. Open-source
payloads should not need to suffer to appease commercial ones.
Instead, this patch introduces a new Kconfig option to explicitly allow
inclusion of GPL code. It will use Kconfig dependencies and/or Makefile
rules to ensure that no GPL code can end up in the final payload if that
option is unset, allowing proprietary payloads to keep working with the
existing BSD-licensed feature set. New features and patches (that are
sufficiently separate and self-contained to allow guarding through this
config option) can choose whether to import GPL code, and need to depend
on this option if they do.
Also clean up all (known) existing uses of GPL code to depend on the new
option, add some recent third-party imports to the LICENSES file, and
relicense the selfboot.c files to BSD with permission of the author.

This patch makes some slight changes to the exception hook interface.
The old code provides a different handler hook for every exception
type... however, in practice all those hook functions often need to look
very similar, so this creates more boilerplate than it removes. The new
interface just allows for a single hook with the exception type passed
as an argument, and the consumer can signal whether the exception was
handled through the return value. (Right now this still only supports
one consumer, but it could easily be extended to walk through a list of
hooks if the need arises.)
Also move the excepton state from an argument to a global. This avoids a
lot of boilerplate since some consumers need to change the state from
many places, so they would have to pass the same pointer around many
times. It also removes the false suggestion that the exception state was
not global and you could have multiple copies of it (which the exception
core doesn't support for any architecture).
On the ARM side, the exception state is separated from the exception
stack for easier access. (This requires some assembly changes, and I
threw in a few comments and corrected the immediate sigils from '$' to
the official '#' while I'm there.) Since the exception state is now both
stored and loaded through an indirection pointer, this allows for some
very limited reentrance (you could point it to a different struct while
handling an exception, and while you still won't be able to return to
the outer-level exception from there, you could at least swap out the
pointer and return back to System Mode in one go).

quite work in the receive direction - the receive FIFO returns read

ARM processors save the PC value in the Link Register when they handle
and exception, but they store it with an added offset (depending on the
exception type). In order to make crashes easier to read and correctly
support more complicated handlers in libpayload, this patch adjusts the
saved PC value on exception entry to correct for that offset.
(Note: The value that we now store is what ARM calls the "preferred
return address". For most exceptions this is the faulting instruction,
but for software interrupts (SWI) it is the instruction after that. This
is the way most programs like GDB expect the stored PC address to work,
so let's leave it at that.)

section B1.8.3.

Seems that the 'if (cursor_enabled)' check in
video_console_fixup_cursor() that was removed in chromium.org 1f880bca0 really
meant to check for 'if (console)'. Looks like the whole video console
driver is built extra robust to not fail no matter how screwed up the
console is, so let's add this missing check here as well. Also fixed up
a few other missing 'if (!console)' checks while I'm at it.
However, what payloads should really be doing is check the return value
of video_(console_)init() and not call the other video functions if that
failed. This also adapts video_console_init() to correctly pass through
the return value for that purpose (something that seems to have been
overlooked in the dd9e4e58 refactoring).

The video console runs a video_console_fixup_cursor() function after
every printed character to make sure the cursor is still in the output
window and avoid overflows. For some crazy reason, this function does
not run when cursor_enabled is false... however, that variable is only
about cursor *visibility*, and it's imperative that we still do proper
bounds checking for our output even if the cursor itself doesn't get
displayed (otherwise we can end up overwriting malloc cookies that cause
a panic on the next free() and other fun things like that).
In fact, there seems to be no reason at all to even keep track of the
cursor visibility state in the generic video console framework (the
specific backends already do it, too), so let's remove that code
entirely. Also set the default cursor visibilty in the corebootfb
backend to 0 since that's consistent with what the other backends do.
BUG=None

I always thought the support for multiple logical SCSI units in the USB
mass storage class was a dead feature. Turns out that it's actually used
by SD card readers that provide multiple slots (e.g. one regular sized
and one micro-SD). Implementing perfect support for that would require a
major redesign of the whole MSC stack, since the one device -> one disk
assumption is deeply embedded in our data structures.
Instead, this patch implements a poor man's LUN support that will just
cycle through all available LUNs (in multiple calls to usb_msc_poll())
until it finds a connected device. This should be reasonable enough to
allow these card readers to be usable while only requiring superficial
changes.
Also removes the unused 'protocol' attribute of usb_msc_inst_t.

So I was debugging this faulty USB SD card reader that would just fail
it's REQUEST SENSE response for some reason (sending the CSW immediately
without the data), cursing those damn device vendors for building
non-compliant crap like I always do... when I noticed that we do not
actually set the Allocation Length field in our REQUEST SENSE command
block at all! We set a length in the CBW, but the SCSI command still has
its own length field and the SCSI spec specifically says that the device
has to return the exact amount of bytes listed there (even if it's 0). I
don't know what's more suprising: that we had such a blatant bug in this
stack for so long, or that this card reader is really the first device
to actually be spec compliant in that regard.
This patch fixes the bug and changes the command block structures to be
a little easier to read (why that field was called 'lun' before is
beyond me... LUN is a transport level thing and should never appear in
the command block at all, for any command). It also fixes a memcpy() in
wrap_cbw() to avoid a read buffer overflow that might expose stack frame
data to the device.

We recently changed the USB stack to detach devices aggressively that we
don't intend to use. This alone is not really a problem, but it
exarcerbates the fact that our device detachment itself is not very
good. We destroy any local info about the device, but we don't properly
disable the offending port. The device keeps thinking that it's active,
and if we later try to reuse that device address for another device
things become confused.
The real fix would be to properly disable all ports that we don't intend
to use. Unfortunately, this isn't really possible in our current
device/hub polymorphism structure, and I don't want to hack a new
disable_port() callback into usbdev_t that really doesn't belong there.
We will only be able to fix this cleanly after we ported all root hubs
to the generic_hub interface.
Until then, an easy workaround is to just avoid reusing addresses as
long as possible. This is firmware, so the chance that we'll ever run
through 127 devices is really small in practice. Even if we ever fix the
underlying issue, it's probably a smart precaution to keep.

The console output driver framework in libpayload is currently built on
the putchar primitive, meaning that every driver's function gets called
one character at a time. This becomes an issue when we add drivers that
could output multiple characters at a time, but have a high constant
overhead per invocation (such as the planned GDB stub, which needs to
wrap a special frame around output strings and wait for an
acknowledgement from the server).
This patch adds a new 'write' function pointer to the
console_output_driver structure as an alternative to 'putchar'. Output
drivers need to provide at least one of the two ('write' is preferred if
available). The CBMEM console driver is ported as a proof of concept
(since it's our most performace-critical driver and should in theory
benefit the most from less function pointer invocations, although it's
probably still negligible compared to the big sprawling mess that is
printf()).
Even with this fix, the problem remains that printf() was written with
the putchar primitive in mind. Even though normal text already contains
an optimization to allow multiple characters at a time, almost all
formatting directives cause their output (including things like
padding whitespace) to be putchar()ed one character at a time.
Therefore, this patch reworks parts of the output code (especially
number printing) to all but remove that inefficiency (directives still
invoke an extra write() call, but at least not one per character). Since
I'm touching printf() core code anyway, I also tried to salvage what I
could from that weird, broken "return negative on error" code path (not
that any of our current output drivers can trigger it anyway).
A final consequence of this patch is that the responsibility to prepend
line feeds with carriage returns is moved into the output driver
implementations. Doing this only makes sense for drivers with explicit
cursor position control (i.e. serial or video), and things like the
CBMEM console that appears like a normal file to the system really have
no business containing carriage returns (we don't want people to
accidentally associate us with Windows, now, do we?).
BUG=chrome-os-partner:18390
TEST=Made sure video and CBMEM console still look good, tried printf()
with as many weird edge-case strings as I could find and compared serial
output as well as sprintf() return value.

To find the coreboot tables, the payload has historically searched for their
signature in a predefined region of memory. This is a little clumsy on x86,
but it works because you can assume certain regions are RAM. Also, there are
areas which are set aside for the firmware by convention. On x86 there's a
forwarding entry which goes in one of those fairly small conventional areas
and which points to the CBMEM area at the end of memory.
On ARM there aren't areas like that, so we've left out the forwarding entry and
gone directly to CBMEM. RAM may not start at the beginning of the address space
or go to its end, and that means there isn't really anywhere fixed you can put
the coreboot tables. That's meant that libpayload has to be configured on a
per board basis to know where to look for CBMEM.
Now that we have boards that don't have fixed amounts of memory, the location
of the end of RAM isn't fixed even on a per board level which means even that
workaround will no longer cut it.
This change makes coreboot pass the location of the coreboot tables to
libpayload using r0, the first argument register. That means we'll be able to
find them no matter where CBMEM is, and we can get rid of the per board search
ranges.
We can extend this mechanism to x86 as well, but there may be more
complications and it's less necessary there. It would be a good thing to do
eventually though.
BUG=None
TEST=Built and booted on nyan. Changed the size of memory and saw that the
payload could still find the coreboot tables where before it couldn't. Built

This patch changes the ENTRY() macro in asm.h to create a new section
for every assembler function, thus providing dcache_clean/invalidate_all
and friends with the same --gc-sections goodness that our C functions
have. This requires a few minor changes of moving around data (to make
sure it ends up in the right section) and changing some libgcc functions
(which apparently need to have two names?), but nothing serious.
(You may note that some of our assembly functions have data, sometimes
even writable, within the same .text section. This has been this way
before and I'm not looking to change it for now, although it's not
totally clean. Since we don't enforce read-only sections through paging,
it doesn't really hurt.)

We've recently fixed a problem where an external hard drive would choke
due to one too many CLEAR_FEATURE(HALT) commands in the XHCI stack with
"libpayload: usb: xhci: Fix STALL endpoint handling". Clearing stall
conditions from within the transfer function is wrong in general... this
is really something that is host controller agnostic and should be left
to the higher-level driver to decide. The mass storage driver (the only
one that should really encounter stalls right now) already contains the
proper amount of clear_stall() calls... any more than that is redundant
and as we found out potentially dangerous.
This patch removes automatic clear stalls from UHCI and OHCI drivers as
well to make things consistent between host controllers.

detach the subtree of devices connected to their ports first (as
generic_hub and by extension XHCI had already been doing).
It also fixes up some missing free() calls and replaces most 'ptr =

This patch changes several cache-related pieces to be cleaner, faster or
more correct. The largest point is removing the old
arm_invalidate_caches() function and surrounding bootblock code to
initialize SCTLR and replace it with an all-assembly function that takes
care of cache and SCTLR initialization to bring the system to a known
state. It runs without stack and before coreboot makes any write
accesses to be as compatible as possible with whatever state the system
was left in by preceeding code. This also finally fixes the dreaded
icache bug that wasted hundreds of milliseconds during boot.

This patch switches every last part of Coreboot on ARM over to Thumb
mode: libpayload, the internal libgcc, and assorted assembly files. In
combination with the respective depthcharge patch, this will switch to
Thumb mode right after the entry point of the bootblock and not switch
back to ARM until the final assembly stub that jumps to the kernel.
The required changes to make this work include some new headers and
Makefile flags to handle assembly files (using the unified syntax and
the same helper macros as Linux), modifying our custom-written libgcc
code for 64-bit division to support Thumb (removing some stale old files
that were never really used for clarity), and flipping the general
CFLAGS to Thumb (some more cleanup there as well while I'm at it).

This patch adds the 10ms TRSTRCY delay between a reset and the following
Set Address command that is required by the USB 2.0 specification to the
EHCI root hub driver. The generic_hub driver that's used for XHCI and
external hubs already included this delay. This is such a glaring
violation of the spec that I'm really amazed how many USB 2.0 devices
we tested before seemed perfectly fine with responding to a Set Address
within 2 microframes of the reset...
It also increases the port reset hold delay by one millisecond to avoid
an ugly race condition on Tegra SoCs: they decided to time the 50ms
themselves instead of relying on the CPU to do it (fair enough), and to
automatically transition Port Reset to 0 and Port Enable to 1 after that
(bad idea). If the CPU's read-modify-write to clear Port Reset races
exactly with the host controller setting Port Enable, we may end up
clearing the bit again and going into the companion controller handoff
path later on. The added millisecond shouldn't cause any problems for
other host controllers and is not a big deal compared to other delays in
this code path.
BUG=chrome-os-partner:26749
TEST=Run several dozen reboot loops with The USB Stick of Death (TM) (a
blue Patriot XT 13fe:5200 with bcdDevice = 1.00), make sure it always
gets detected correctly.

This patch enables the OHCI driver to use DMA memory, which is necessary
for ARM systems where DMA devices are not cache coherent. I really only
need this to test some later OHCI changes, but it was easy enough...
copied almost verbatim from ehci.c.

- Remove the call to clear_stall in xhci_reset_endpoint because we will
call clear_stall from the mass-storage driver.
- Remove the xhci_reset_endpoint call from xhci_bulk on STALL since we
will reset on the next transfer anyway.
- Remove the clear_halt parameter from xhci_bulk since it's now unused.

libpayload's kconfig is totally incompatible with other kconfig versions,
today. Using other versions just doesn't work any more, so don't use the
overridable $(obj)/util/kconfig path. Choose a path that reflects the
incompatibility: $(obj)/util/lp_kconfig, instead.
This whole every-(sub)project-has-it's-own-patched-kconfig-version makes
me really, really sad :'-(

If a port is connected before and after an xhci controller reset, the
PORTSC CSC bit may not be asserted. Add an additional check in
xhci_rh_port_status_changed for the PRC bit so we can correctly handle
ports in such a state.

The generic roothub reset port function is overly broad and does some
things which may be undesirable, such as issuing multiple resets to a
port if the reset is deemed to have finished too quickly. Remove the
generic function and replace it with a controller-specific function,
currently only implemented for xhci.

Pass -ggdb3 to the compiler when building libpayload, -ggdb so that it uses
"the most expressive format available", and 3 so that the debugging level is
set to 3, the highest value currently supported. The debugging information can
be stripped by the payload consuming the library, and will definitely be
stripped by cbfstool when installing that payload into an image.

This patch fixes the remaining few bugs in our shiny new cache iteration
by set/way/level algorithm to actually make it work: It makes it start
from cache level 0 (previously it would always start at LoC and be
"done" instantly), fixes up the two shifts that isolate the set bits at
the end (which didn't seem to account for the fact that the first shift
affects the second), and throws an S bit on that last shift so that it
actually affects the conditionals after it.
In addition, also moves the next_level block to the top so that we can
share (and thus eliminate) some code at initialization, and turns the
whole thing into a thrice-instantiated macro to create functions that
fit our existing interface.

The memcpy/memset/memmove assembly implementations have been taken from
U-Boot, which originally got them from Linux. I turns out that they are
actually not that bad, but they could use an update. This patch pulls in
the current Linux upstream versions of those files, removing some old
U-Boot cruft such as checking whether the two pointers in a memcpy() are
equal (really now?) or side-stepping the R8 register because it was used
for special purposes. It also returns to the good old Linux
ENTRY/ENDPROC macros since we have them now anyway, and straightens out
the W() macro in preparation for unified thumb support.
