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.

If a programming error is detected, die can be used to print a message and
stop execution similar to failing an assert. There's also a "die_if" function
which is conditional.
die functions, like asserts, should be used to trap programming errors and not
when the hardware does something wrong. If all code was written perfectly, no
die function would ever be called. In other words, it would be appropriate to
use die if a function was called with a value that was out of bounds or if
malloc failed. It wouldn't be appropriate if an external device doesn't
respond.
In the future, the die family of functions might print a stack trace or show
other debugging info.

"Hey guys, I have this awesome idea! How about we put a huge array
filled with 0xa5 into the data segment of our uncompressed romstage

Guess it pays off to just hexdump our image and sanity-check it top to
bottom every once in a while...
Also reduces the size because 8K is crazy just to print a bunch of
registers (256 bytes ought to be enough for anybody).

arm: Remove exception_test()
The exception_test() mechanism might have been useful when exceptions
were first implemented, but now that they are pretty stable it's really
not necessary anymore (especially not on every single boot in production
Chromebooks). It forces a simple unaligned access, and as we start
having exceptions in stages that might not have paging turned on yet,
it's better to remove that completely.
Also removed the duplicated implementations of SCTLR-stuff and switched
to the existing ones in cache.h.

Add the option to coreboot to set the SeaBIOS buffers below 0xC0000.
This is a requirement on the Intel Rangeley processor
because it is designed so that only the processor can write
the higher memory areas. This prevents USB and SATA from bus-mastering
into the buffers when they're set in the typical 0xE0000 area.
This will be set to Y unless defaulted to N by the mainboard or
chipset.

for us to throw away a perfectly fine register on this already pretty
constrained architecture.
Also removed a config.h inclusion from the Makefile because that should
really be done inside the C files.

There are ARM systems which are essentially heterogeneous multicores where
some cores implement a different ARM architecture version than other cores. A
specific example is the tegra124 which boots on an ARMv4 coprocessor while
most code, including most of the firmware, runs on the main ARMv7 core. To
support SOCs like this, the plan is to generalize the ARM architecture so that
all versions are available, and an SOC/CPU can then select what architecture
variant should be used for each component of the firmware; bootblock,
romstage, and ramstage.

ARM: Split out ARMv7 code and make it possible to have other arch versions.
We don't always want to use ARMv7 code when building for ARM, so we should
separate out the ARMv7 code so it can be excluded, and also make it possible
to include code for some other version of the architecture instead, all per
build component for cases where we need more than one architecture version
at a time.
The tegra124 bootblock will ultimately need to be ARMv4, but until we have
some ARMv4 code to switch over to we can leave it set to ARMv7.

This patch represents a major overhaul of the USB enumeration code in
order to make it cleaner and much more robust to weird or malicious
devices. The main improvement is that it correctly parses the USB
descriptors even if there are unknown descriptors interspersed within,
which is perfectly legal and in particular present on all SuperSpeed
devices (due to the SuperSpeed Endpoint Companion Descriptor).
In addition, it gets rid of the really whacky and special cased
get_descriptor() function, which would read every descriptor twice
whether it made sense or not. The new code makes the callers allocate
descriptor memory and only read stuff twice when it's really necessary
(i.e. the device and configuration descriptors).
Finally, it also moves some more responsibilities into the
controller-specific set_address() function in order to make sure things
are initialized at the same stage for all controllers. In the new model
it initializes the device entry (which zeroes the endpoint array), sets
up endpoint 0 (including MPS), sets the device address and finally
returns the whole usbdev_t structure with that address correctly set.
Note that this should make SuperSpeed devices work, but SuperSpeed hubs
are a wholly different story and would require a custom hub driver
(since the hub descriptor and port status formats are different for USB
3.0 ports, and the whole issue about the same hub showing up as two
different devices on two different ports might present additional
challenges). The stack currently just issues a warning and refuses to
initialize this part of the hub, which means that 3.0 devices connected
through a 3.0 hub may not work correctly.

This patch removes the confusing concept of a special "xhci_speed" with
a different numeric value from the usual speed used throughout the USB
core (except for the places directly interacting with the xHC, which are
explicitly marked). It also moves the MPS0 decoding function into the
core and moves some definitions around in preparation of later changes
that will make the stack SuperSpeed-ready. It makes both set_address
implementations share a constant for the specification-defined
SetAddress() recovery delay and removes pointless additional delays from
the non-XHCI version.

This patch fixes a bug in the XHCI stack that occurs when a multi-TRB TD
times out before the last TRB is processed. The driver will correctly
issue a Stop Endpoint command in that case, but the xHC will still
preserve the transfer state and just pick up right after that on the
next doorbell ring. It will then process the leftover TRBs from the old
TD the next time a transfer is issued. (cf. XHCI 4.6.9)
We fix this by changing the existing xhci_reset_endpoint() calls in
transfer functions to not only trigger on Halted (2) and Error (4), but
also on Stopped (3). That function will not actually issue a Reset
Endpoint command in this case, but it will nuke the whole transfer ring
and issue a Set TR Dequeue Pointer command, which is sufficient (though
slightly overkill) to solve our problem.

While the 8250 compatible serial port driver is primarily useful on x86
systems because it works with the legacy x86 com ports, some devices which
aren't x86 based have 8250 compatible UARTs as well. This change renames the
CONFIG_X86_SERIAL_CONSOLE option to the more general and direct
CONFIG_8250_SERIAL_CONSOLE and fixes up the dependencies so that non-x86
systems can enable the driver, although it will default to on on x86 and off
otherwise.
Also, the default IO port address that's added to the sysinfo structure on x86
and which is intended to be overwritten by a value in the coreboot tables is
not used on ARM. That variable is adjusted so that it's more clear it's a
default value, and made dependent on x86 since that's the only place its value
is actually used.

This patch fixes the following minor bugs in the USB stack:
1. Ensure that all dynamically allocated device structures are cleaned
on detachment, and that the device address is correctly released again.
2. Make sure MSC and HID drivers notice missing endpoints and actually
detach the device in that case (to prevent it from being used).
3. Make sure XHCI-specific set_address() cleans up all data structures
on failure.
4. Fix broken Slot ID range check that prevented XHCI devices from being
correctly cleaned up.

The USB MSC device structure contains a "ready" state that can be either
"ready", "not ready" or "detached". The last one can only be assigned
when the device is completely unresponsive and gets forcefully logically
detached via usb_detach_device(). This call (at least in the current
version) also calls all destructors and frees the complete usbdev_t
structure (including the MSC specific part), which unfortunately makes
storing the "detached" state in that very structure a little pointless.
This patch reduces the "ready" value to a simple boolean and makes sure
that all detachment cases immediately return from the MSC driver,
carefully avoiding any use-after-free opportunities.

Since the DMA memory is allocated by Coreboot (outside of the payload's
linker script), it won't get zeroed upon loading like the heap.
Therefore, a warm reboot that doesn't reset memory may leave stale
malloc cookies lying around and misinterpret them as memory that is
still in use on the next boot. After several boots this may fill up the
whole DMA memory and lead to OOM conditions.
Therefore, this patch explicitly wipes the first cookie in
init_dma_memory() to prevent that from happening. It also expands the
existing memory allocator debugging code to cover the DMA parts, which
was very helpful in identifying this particular problem.

This patch updates the libpayload XHCI stack to run on ARM CPUs (tested
with the DWC3 controller on an Exynos5420). Firstly, it adds support for
64-byte Slot/Endpoint Context sizes. Since the existing context handling
code represented the whole device context as a C struct (whose size has
to be known at compile time), it was necessary to refactor the input and
device context structures to consist of pointers to the actual contexts
instead.
Secondly, it moves all data structures that the xHC accesses through DMA
to cache-coherent memory. With a similar rationale as in the ARM patches
for EHCI, using explicit cache maintenance functions to correctly handle
the actual transfer buffers in all cases is presumably impossible.
Instead this patch also chooses to create a DMA bounce buffer in the
XHCI stack where transfer buffers which are not already cache-coherent
will be copied to/from.

This patch makes the EHCI driver work on ARM platforms which usually do
not support automatic cache snooping. It uses the new DMA memory
mechanism (which needs to be correctly set up in the Coreboot mainboard
code) to allocate all EHCI-internal communication structures in
cache-coherent memory, and cleans/invalidates the externally supplied
transfer buffers in Bulk and Control functions with explicit calls as
necessary.

libpayload: ehci: Cache management is hard, let's go copying...
It turns out that my previous commit to make the EHCI stack cache aware
on ARM devices wasn't quite correct, and the problem is actually much
trickier than I thought. After having some fun with more weird transfer
problems that appear/disappear based on stack alignment, this is my
current worst-case threat model that any cache managing implementation
would need to handle correctly:
Some upper layer calls ehci_bulk() with a transfer buffer on its stack.
Due to stack alignment, it happens to start just at the top of a cache
line, so up to 64 - 4 bytes of ehci_bulk's stack will share that line.
ehci_bulk() calls dcache_clean() and initializes the USB transfer.
Between that point and the call to dcache_invalidate() at the end of
ehci_bulk(), any access to the stack variables in that cache line (even
a speculative prefetch) will refetch the line into the cache. Afterwards
any other access to a random memory location that just happens to get
aliased to the same cache line may evict it again, causing the processor
to write out stale data to the transfer buffer and possibly overwrite
data that has already been received over USB.
In short, any dcache_clean/dcache_invalidate-based implementation that
preserves correctness while allowing any arbitrary (non cache-aligned)
memory location as a transfer buffer is presumed to be impossible.
Instead, this patch causes all transfer data to be copied to/from a
cache-coherent bounce buffer. It will still transfer directly if the
supplied buffer is already cache-coherent, which can be used by callers
to optimize their transfers (and is true by default on x86).

This patch adds a mechanism to set aside a region of cache-coherent
(i.e. usually uncached) virtual memory, which can be used to communicate
with DMA devices without automatic cache snooping (common on ARM)
without the need of explicit flush/invalidation instructions in the
driver code.
This works by setting aside said region in the (board-specific) page
table setup, as exemplary done in this patch for the Snow and Pit
boards. It uses a new mechanism for adding board-specific Coreboot table
entries to describe this region in an entry with the LB_DMA tag.
Libpayload's memory allocator is enhanced to be able to operate on
distinct types/regions of memory. It provides dma_malloc() and
dma_memalign() functions for use in drivers, which by default just
operate on the same heap as their traditional counterparts. However, if
the Coreboot table parsing code finds a CB_DMA section, further requests
through the dma_xxx() functions will return memory from the region
described therein instead.

The current USB hub code always clears the port status change after
checking it, regardless of whether it was set in the first place. Since
this check runs on every poll, it might create a race condition where
the port status changes right between the GET_PORT_STATUS and the
CLEAR_FEATURE(C_PORT_CONNECT), thus clearing the statrus change flag
before it was ever read. Let's add one extra if() to avoid that possible
headache.

The USB bulk and control transfer functions in libpayload currently
always return 0 for success and 1 for all errors. This is sufficient for
current use cases (essentially just mass storage), but other classes
(like certain Ethernet adapters) need to be able to tell if a transfer
reached the intended amount of bytes, or if it fell short.
This patch slightly changes that USB API to return -1 on errors, and the
amount of transferred bytes on successes. All drivers in the current
libpayload mainline are modified to conform to the new error detection
model. Any third party users of this API will need to adapt their
if (...<controller>->bulk/control(...)) checks to
if (...<controller>->bulk/control(...) < 0) as well.
The host controller drivers for OHCI and EHCI correctly implement the
new behavior. UHCI and the XHCI stub just comply with the new API by
returning 0 or -1, but do not actually count the returned bytes.

The current XHCI code only sets IOC on the last TRB of a TD, and
doesn't set ISP anywhere. On my Synopsys DesignWare3 controller, this
won't generate an event at all when we have a short transfer that is not
on the last TRB of a TD, resulting in event ring desync and everyone
having a bad time. However, just setting ISP on other TRBs doesn't
really make for a nice solution: we then need to do ugly special casing
to fish out the spurious second transfer event you get for short
packets, and we still need a way to figure out how many bytes were
transferred. Since the Short Packet transfer event only reports
untransferred bytes for the current TRB, we would have to manually walk
the rest of the unprocessed TRB chain and add up the bytes. Check out
U-Boot and the Linux kernel to see how complicated this looks in
practice.
Now what if we had a way to just tell the HC "I want an event at exactly
*this* point in the TD, I want it to have the right completion code for
the whole TD, and to contain the exact number of bytes written"? Enter
the Event Data TRB: this little gizmo really does pretty much exactly
what any sane XHCI driver would want, and I have no idea why it isn't
used more often. It solves both the short packet event generation and
counting the transferred bytes without requiring any special magic in
software.

access the banked registers of SVC mode from a different exception mode,
it changes Coreboot (and its payloads) to run in System mode instead. As
both modes can execute all privileged instructions, this should not have
any noticeable effect on firmware operation (please correct me if I'm
wrong!).

When libpayload header files are included in the payload itself, it's possible
that the payloads config settings will conflict with the ones in libpayload.
It's also possible for the libpayload config settings to conflict with the
payloads. To avoid that, the libpayload config settings have _LP_ (for
libpayload) added to them. The symbols themselves as defined in the Config.in files
are still the same, but the prefix added to them is now CONFIG_LP_ instead of just

armv7: clean but do not invalidate caches between stages
This cleans the caches without invalidating them between stages. The
dcache content should still be valid when the next stage begins, so
we should see a small performance gain.

ARM: Fix cache cleaning operation.
There was no behavior defined for OP_DCCSW in dcache_op_set_way, so it
silently did nothing. Since we started using that to clean the cache between

Instead of creating the SeaBIOS .config file for QEMU, then changing
things to be coreboot specific, create a default config for coreboot,
then run olddefconfig to use the SeaBIOS defaults as they're set for
coreboot. This leads to a cleaner config.
Note that CONFIG_THREAD_OPTIONROMS defaults to enabled for SeaBIOS if
we're building for coreboot, so I reversed the logic.
I *ASSUMED* that leaving CONFIG_QEMU_HARDWARE=y and CONFIG_DEBUG_IO=y
previously was an oversight. If this is not correct, please let me
know and I'll add them it back in. SeaBIOS disables these by default
if building for coreboot.

and pointers for virtual addresses things become much cleaner and we

SeaBIOS 1.7.4 was released in December 2013 [1] and, besides other
things, supports writing debug messages to CBMEM console.
The new SeaBIOS Kconfig option `DEBUG_COREBOOT` has to be added to the
SeaBIOS configuration file `.config` as otherwise the SeaBIOS build
from within coreboot (`PAYLOAD_SEABIOS`) is interrupted as it is
detected as a new option.
This option was already added and enabled in commit 7c1a49bc [1]
SeaBIOS: have coreboot pass the choice to run optionroms in parallel
so SeaBIOS messages are now written to the CBMEM console.
Successfully tested on the Asus M2V-MX SE.

The hexdump function was added to libpayload recently, but its source file was
never added to the Makefile so it wasn't compiled or linked in.

The EHCI driver defines a maximum transfer timeout of two seconds. The
comments state that during tests the maximum amount of required transfer
time was for the SCSI TEST_UNIT_READY command on certain devices. We
have now observed a USB device (Patriot Memory 13fe:3100) that can NAK
this command for slightly more than two seconds. It will also completely
fail if the timeout hits, since it gets confused by the subsequent CSW
retry/recovery mechanism and starts producing babble errors. This patch
increases the timeout to three seconds to circumvent this problem.
To test, boot a Falco from a red-black RageXT USB stick.
