log2(1) is 0 and log2(0) is -1. If we have the int64_t 0xffffffff then
log2(0xffffffff >> 31) = log2(0x1) = 0, so the current reduction code
would not shift. That's a bad idea, though, since 0xffffffff when
interpreted as an int32_t would become a negative number.
We need to always shift one more than the current code does to get a
safe reduction. This also means we can get rid of another compare/branch
since -1 is the smallest result log2() can return, so the shift can no
longer go negative now.

particular, this allows depthcharge to control the state of an

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).

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).

remain constant across iterations, due to 0-length elements or integer

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.

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.

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.

not support class-specific control requests (Get Max LUN and Bulk-Only
Reset). We'd like to identify/enumerate the device via

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 a99ed13e33.

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

F2 are working.

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'.

In order to allow payloads to use the keyboard when this happens a

Pointer math with void pointers is illegal in many compilers, though it
works with GCC because it assumes size of void to be 1. In this particular
situation, dev->buf is already pointer to u8, and there's no need to convert

The arm32 GDB architecture code contains a little hack that allows it to
(sort of) correctly deal with a reentrant exception triggered from
within the GDB stub. The main logic for this isn't really arm32 specific
and could be useful for other architectures as well, so factor it out
into a separate function.

This patch reworks the arm64 exception handling to be more similar to
how it works on arm32. This includes a bunch of features like actually
saving and restoring more exception state in the exception_state
structure and supporting the same sort of partial reentrancy that is
useful for GDB. Since there's no instruction to directly load into or
store out of SP on arm64, we can't do quite the same thing where we use
that to read an exception_state_ptr variable right after exception entry
when no other register is available. But we can do something very
similar by (ab-)using the "high" stack pointer (SP_EL2) as a pointer to
the exception_state struct and providing a function to change it.

This patch adds the new, faster architectural register accessors to
libpayload that were already added to coreboot in CB:27881. It also
hardcodes the assumption that coreboot payloads run at EL2, which has
already been hardcoded in coreboot with CB:27880 (see rationale there).
This means we can drop all the read_current/write_current stuff which
added a lot of unnecessary helpers to check the current exception level.
This patch breaks payloads that used read_current/write_current
accessors, but it seems unlikely that many payloads deal with this stuff
anyway, and it should be a trivial fix (just replace them with the
respective _el2 versions).
Also add accessors for a couple of more registers that are required to
enable debug mode while I'm here.

I'm going to deprecate exception_install_hook and remove it in a follow
