The latest Intel FSP advertises xHCI v1.2 chipset support, so update
libpayload to include that version. No critical changes were identified
in review of the xHCI v1.2 spec, and booting from USB works with the
included change as expected.

I rushed CB:40895 in to fix a bug only to introduce another. xhci_init()
no longer crashes, but it doesn't correctly initialize the XHCI
controller either, and unfortunately the error messages are all hidden
behind USB_DEBUG. This patch fixes the incorrect address calculation to
what it was before CB:39838.

The QEMU XHCI driver does not implement the Port Change Detect bit
in the USBSTS register. As a result no devices are attached without
looking at each port individually.
Detect this as a quirk based on the QEMU XHCI controller PCI ID,
and apply it to the root hub quirk list so it can get used by the
generic hub driver to skip this check.
With this change an attached USB mass storage device is detected and
able to boot when supplied to qemu:
-drive if=none,id=usbmsc,format=raw,file=/tmp/disk.img
-device qemu-xhci,id-xhci
-device usb-storage,bus=xhci.0,drive=usbmsc

memcpy() is meant to be used on normal memory and often implemented with
architecture-specific optimizations to make that as performant as
possible. MMIO registers often have special access restrictions that may
be incompatible with whatever memcpy() does. For example, on arm64 it
uses the LDP (load pair) to load 16 bytes at a time, which makes 4-byte
MMIO registers unhappy.
This patch removes the caching of the XHCI capreg registers and changes
it back to a pointer. The CAP_GET() macro is still accessing a full
(non-bitfield) uint32_t at the end so this should still generate a
4-byte access (which was the goal of the original change in CB:39838).

`lib_sysinfo->serial` is a virtual pointer into coreboot tables.
It's not valid across relocation. Accessing the wrong value during
relocation of FILO resulted in a hang with DEBUG_SEGMENT and UART
console enabled. Work around that by caching the whole table entry
locally.
An alternative would be to revise `sysinfo`, to contain no virtual
pointers to anything outside the payload.

The QEMU XHCI controller does not support byte/word reads from the
capability register and it expects dword reads only.
In order to make this work move the access of the capability
register fields to use macros instead of a packed struct bitfield.
This issue was filed upstream:
https://bugs.launchpad.net/qemu/+bug/1693050
The original fix attempt in 2012 was not effective:
https://github.com/qemu/qemu/commit/6ee021d41078844df60a3a466e3829a3e82776f3
With this change the controller is detected properly by the libpayload
USB drivers.

Our realloc() works (somewhat suboptimally) by free()ing the existing
allocation and then reallocating it wherever it fits. If there was free
space before the old location, this means the new allocation may be
before the old one, and if the free space block is smaller than the old
allocation it may overlap. Thus, we should be moving memmove() instead
of memcpy() to move the block over.
This is not a problem in practice since all our existing memcpy()s are
simple iterate and copy front to back implementations which are safe for
overlaps when the destination is in front of the source. but it's still
the more correct thing to do (in case we ever change our memcpy()s to do
something more advanced or whatever).

cbfs_get_handle() and cbfs_get_attr() are both looping over elements to
find a particular one. Each element header contains the element's
length, which is used to compute the next element's offset. Invalid or
corrupted CBFS files could lead to infinite loops where the offset would
remain constant across iterations, due to 0-length elements or integer
overflows in the computation of the next offset.
This patch makes both functions more robust by adding a check that
ensure offsets are strictly monotonic. Instead of infinite looping, the
functions are now printing an ERROR and returning a NULL value.

This patch makes libpayload enable the instruction cache as the very
first thing, which is similar to how we treat it in coreboot. It also
prevents the icache from being disabled again during mmu_disable() as
part of the two-stage page table setup in post_sysinfo_scan_mmu_setup().
It replaces the existing mmu_disable() implementation with the assembly
version from coreboot which handles certain edge cases better (see
CB:27238 for details).
The SCTLR flag definitions in libpayload seem to have still been
copy&pasted from arm32, so replace with the actual arm64 defintions from
coreboot.

According to the POSIX standard, %p is supposed to print a pointer "as
if by %#x", meaning the "0x" prefix should automatically be prepended.
All other implementations out there (glibc, Linux, even libpayload) do
this, so we should make coreboot match. This patch changes vtxprintf()
accordingly and removes any explicit instances of "0x%p" from existing
format strings.
How to handle zero padding is less clear: the official POSIX definition
above technically says there should be no automatic zero padding, but in
practice most other implementations seem to do it and I assume most
programmers would prefer it. The way chosen here is to always zero-pad
to 32 bits, even on a 64-bit system. The rationale for this is that even
on 64-bit systems, coreboot always avoids using any memory above 4GB for
itself, so in practice all pointers should fit in that range and padding
everything to 64 bits would just hurt readability. Padding it this way
also helps pointers that do exceed 4GB (e.g. prints from MMU config on
some arm64 systems) stand out better from the others.

To avoid trampling over interesting exception artifacts on the real
stack, our arm64 systems switch to a separate exception stack when
entering an exception handler. We don't want that to use up too much
SRAM so we just set it to 512 bytes. I mean it just prints a bunch of
registers, how much stack could it need, right?
Quite a bit it turns out. The whole vtxprintf() call stack goes pretty
deep, and aarch64 generally seems to be very generous with stack space.
Just the varargs handling seems to require 128 bytes for some reason,
and the other stuff adds up too. In the end the current implementation
takes 1008 bytes, so bump the exception stack size to 2K to make sure it
fits.

This patch changes all existing instances of clrsetbits_leXX() to the
new endian-independent clrsetbitsXX(), after double-checking that
they're all in SoC-specific code operating on CPU registers and not
actually trying to make an endian conversion.
This patch was created by running
sed -i -e 's/\([cs][le][rt]bits\)_le\([136][624]\)/\1\2/g'
across the codebase and cleaning up formatting a bit.

This patch removes the recently added update8/16/32/64() API and
replaces it with clrsetbits8/16/32/64(). This is more in line with the
existing endian-specific clrsetbits_le16/32/64() functions that have
been used for this task on some platforms already. Rename clrsetbits_8()
to clrsetbits8() to be in line with the new naming.
Keep this stuff in <device/mmio.h> and get rid of <mmio.h> again because
having both is confusing and we seem to have been standardizing on
<device/mmio.h> as the standard arch-independent header that all
platforms should include already.
Also sync libpayload back up with what we have in coreboot. (I'm the
original author of the clrsetbits_le32-definitions so I'm relicensing
them to BSD here.)

In interactive payloads, the USB stack's poll procedure is implicitly
called from the UI loop. Since all USB control transfers are handled
synchronously, polling hubs with these slows the UI significantly down.
So switch to interrupt transfers that are done asynchronously and only
perform control transfers when the hub reported a status change.
We use the interrupt endpoint's max packet size instead of the theo-
retical transfer length of `(bNrPorts + 1) / 8` as Linux' code mentions
hubs that return too much data.

We're planning to have a use case with a custom USB device that
implements the USB mass storage protocol on its bulk endpoints, but does
not have the normal MSC class/protocol interface descriptors and does
not support class-specific control requests (Get Max LUN and Bulk-Only
Reset). We'd like to identify/enumerate the device via
usb_generic_create() in our payload but then reuse all the normal MSC
driver code. In order to make that possible, this patch factors a new
usb_msc_force_init() function out of usb_msc_init() which will
initialize an MSC device without checking its descriptors. It also adds
some "quirks" flags that allow devices registered this way to customize
behavior of the MSC stack.

Some broken USB mass storage devices send another zero-length packet at
the end of the data part of a transfer if the amount of data was evenly
divisible by the packet size (which is pretty much always the case for
block reads). This packet will get interpreted as the CSW and screw up
the MSC state machine.
This patch works around this issue by retrying the CSW transfer when it
was received as exactly 0 bytes. This is the same mitigation the Linux
kernel uses and harmless for correctly behaving devices. Also tighten
validation of the CSW a little, making sure we verify the length before
we read any fields and checking the signature in addition to the tag.

Many peripheral drivers across different SoCs regularly face the same
task of piping a transfer buffer into (or reading it out of) a 32-bit
FIFO register. Sometimes it's just one register, sometimes a whole array
of registers. Sometimes you actually transfer 4 bytes per register
read/write, sometimes only 2 (or even 1). Sometimes writes need to be
prefixed with one or two command bytes which makes the actual payload
buffer "misaligned" in relation to the FIFO and requires a bunch of
tricky bit packing logic to get right. Most of the times transfer
lengths are not guaranteed to be divisible by 4, which also requires a
bunch of logic to treat the potential unaligned end of the transfer
correctly.
We have a dozen different implementations of this same pattern across
coreboot. This patch introduces a new family of helper functions that
aims to solve all these use cases once and for all (*fingers crossed*).

The documented return value for strlcat is horribly wrong, as is the
return value itself. It should not return the number of appended bytes,
but rather the length of the concatenated string. From the man page:
The strlcpy() and strlcat() functions return the total length of the
string they tried to create. For strlcpy() that means the length of
src. For strlcat() that means the initial length of dst plus the
length of src. While this may seem somewhat confusing, it was done
to make truncation detection simple.
This change is more likely to fix existing code than break it, since
anyone who uses the return value of strlcat will almost certainly rely
on the standard behaviour rather than investigate coreboot's source code
to see that we have a quirky version.

Documentation is scarce on the matter, however the related coreboot
code suggests that after the ACK, the keyboard also sends the result
of the self test (passed/failed). It looks like this result is never
consumed here, probably resulting in further confusion for later com-
mands.
Let's revert this for now (if it's not too late for the 4.10 release)
and break things later again. IMHO, due to the fact that there are
dozens of different keyboard controller and keyboard implementations
and no accurate specification followed, such changes should be tested
on a lot of hardware before merge.
This reverts commit a99ed13e3397bc536012120aab8cadb827913863.

CB:32951 ("libpayload: Reset PS/2 keyboard") added a call to reset
keyboard and check the return value of keyboard_cmd() to compare
against I8042_KBCMD_ACK. However, keyboard_cmd() already checks for
ACK and returns 1 or 0 based on whether ACK is received.
This change fixes the check introduced by CB:32951 to compare against
0 just like the other checks for keyboard_cmd(). Additionally, it adds
error messages for all failed commands in keyboard_init() to make the
prints consistent in case of failure.

Loading a libpayload based payload like coreinfo or FILO from SeaBIOS or
GRUB pressing keys does not give the expected results.
For example, pressing F1 gives the character 24 translated to scan code
6a. ESC for example 43 (111) in coreinfo loaded from SeaBIOS on QEMU
Q35.
The problem is not reproducible using the payload directly, that means
without SeaBIOS or GRUB. The problem seems to be, that those have already
initialized the PS/2 controller and AT keyboard.
Comparing it with coreboot’s PS/2 keyboard code, the keyboard needs to
be reset. That seems to fix the issue, when the keyboard was initialized
before.
TEST=Build coreboot for QEMU Q35 with SeaBIOS, and coreinfo as secondary
payload. Run
qemu-system-i386 -M q35 -L /dev/shm -bios build/coreboot.rom -serial stdio
press 3 to select the coreinfo payload, and verify that the keys F1 and
F2 are working.
Same with coreinfo loaded from GRUB on the ASRock E350M1.

Depthcharge uses the keyboard type to help determine whether
it can trust the keyboard for security-sensitive confirmations.
Currently it trusts anything except usb, but now there's a need
to distrust ec-based ps/2 keyboards that are associated with untrusted
ECs. To help facilitate this, coreboot needs to report more
details about non-usb keyboards, so this change replaces the current
instances of unknown with enum values that distinguish uart and gpio
from ec-based keyboards.

Our strtol() and strtoull() function contain almost exactly the same
code. This is a) bad in general and b) may cause the code to get out of
sync, such as it recently happened with CB:32029.
This patch changes strtol() to be based on strtoull() so that the main
parsing code exists only once, and also adds a strtoll() to round off
the library. Also fix the bounds imposed by strtoul() to be based on the
actual length of a 'long', not hardcoded to 32-bits (which is not
equivalent on all architectures).

Our current limits.h only provides (U)INT_MAX constants. This patch adds
most others expected by POSIX. Since some of these may be different
depending on architecture (e.g. 'long' is 32-bit on x86 and 64-bit on
arm64), provide a definition that will automatically figure out the
right value for the data model the compiler is using (as long as it's
using two's complement for signed integers, which I think we can assume
these days).

don't quite work the way they are written anymore. Also, several of the

double-evaluation safety while I'm here anyway... and I have no idea why
this ever depended on CONFIG_LP_USB, that just seems like a typo.

I just got hit by a double-evaluation bug again, it's time to attempt
to fix this once more. Unfortunately there are several issues that don't
make this easy:
- bitfield variables don't support typeof()
- local macro variables that shadow others trigger -Werror=shadow
- sign warnings with integer literal and unsigned var in typeof-MIN()
- ({ statement expressions }) can not be used outside functions
- romcc doesn't support any of the fancy GCC/clang extensions
This patch tries to address all of them as far as possible with macro
magic. We don't have the technology to solve the bitfield and
non-function context issues yet (__builtin_choose_expr() still throws a
"no statement expression outside a function" error if it's only in the
branch that's not chosen, unfortunately), so we'll have to provide
alternative macros for use in those cases (and we'll avoid making
__ALIGN_MASK() double-evaluation safe for now, since it would be
annoying to do that there and having an alignment mask with side
effects seems very unlikely). romcc can continue using unsafe versions
since we're hopefully not writing a lot of new code for it. Sign
warnings can be avoided in literal/variable comparisons by always using
the type of the variable there. Shadowing is avoided by picking very
explicit local variable names and using a special __COUNTER__ solution
for MIN() and MAX() (the only ones of these you're likely to nest).
Also add DIV_ROUND_UP() to libpayload since it's a generally quite
useful thing to have.

strtoull() can optionally take a second pointer as an out-parameter that
will be adjusted to point to the end of the parsed string. This works
almost right, but misses two important edge cases: firstly,when the
parsed string is "0", the function will interpret the leading '0' as an
octal prefix, so that the first actually parsed digit is already the
terminating '\0' byte. This will cause the function to early abort,
which still (correctly) returns 0 but doesn't adjust *endptr.
The early abort is pointless anyway -- the only other thing the function
does is run a for-loop whose condition is the exact inverse (so it's
guaranteed to run zero iterations in this case) and then adjust *endptr
(which we want). So just take it out. This also technically corrects the
behavior of *endptr for a completely invalid string, since the strtoull
man page says
> If there were no digits at all, strtoul() stores the original value of
> nptr in *endptr (and returns 0).
The second issue occurs when the parsed string is "0x" without another
valid digit behind it. In this case, we will still jump over the 0x
prefix so that *endptr is set to the first byte after that. The correct
interpretation in this case is that there is no 0x prefix, and instead a
valid 0 digit with the 'x' being invalid garbage at the end. By not
skipping the prefix unless there's at least one valid digit after it, we
get the correct behavior of *endptr pointing to the 'x'.
