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.
BUG=b:134366527
TEST=Verified that logs do not contain "ERROR: Keyboard reset failed"
anymore.

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.

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'.

If keys are pressed at boot some keyboard controllers will not
properly respond with an ACK to commands, which results in the
keyboard_init function aborting before it adds the keyboard to the
input device list.
This same keyboard controller will manage to properly return keyboard
data when keys are pressed later, so it is possible for it to be
functional in the payload even if it does not respond properly to
every command during initialization.
In order to allow payloads to use the keyboard when this happens a
new Kconfig option is added to ignore the keyboard ACK response and
always add the keyboard to the input device list. This option is
disabled by default and must be enabled by the specific boards that
need it.

Rather than attempt to maintain patches against upstream Tianocore, use
MrChromebox's coreboot framebuffer branch as the default build target.
Rework the Makefile to default to MrChromebox's coreboot_fb branch, but
also allow for aribitrary commits from upstream Tianocore to be used
as build targets.
Ensure the branch is synced on each build, as long as working directory
is clean, and that switching between commits or trees is handled sanely.
Eliminate TIANOCORE_MASTER as a selectable build target, since unpatched
it is unlikely to boot on any device. It can easily be specified via
the 'revision' option if desired.
Test: build for the default stable target, for upstream/master
as the specified revision, and for an arbitrary valid commit hash.

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.

This method has a pause instruction to help the CPU relax a little bit.
Measuring grunt it saves about 80mW.
BUG=b:109749762
TEST=Made sure that grunt boots.

Replace _delay with an arch_ndelay(). This way each arch can setup their
own delay mechanism.
BUG=b:109749762
TEST=Verified delay's still work on grunt.

The apic_delay method will halt the CPU and wait for a timer interrupt
to fire. I went with usec because nsec is too granular to guarantee.
This method will be called from an arch_ndelay() method when the delay
is large enough to justify a sleep.
BUG=b:109749762
TEST=Tested it on grunt by changing the _delay method to call
apic_delay().

This is just the bare minimum required to initialize the APIC. I only
support xAPIC and chose not to support x2APIC. We can add that
functionality later when it's required.
I also made the exception dispatcher call apic_eoi so that the callbacks
won't forget to call it.
BUG=b:109749762
TEST=Booted grunt and verified that depthcharge continued to function
and that linux booted correctly. Also verified GDB still works.

I need to setup the APIC timer to fire interrupts. I would like to reuse
the existing interrupt table. So I extended it to support user defined
interrupts. I just added all 255 vectors so there wouldn't need to be
any additional build time configuration.
I'm going to deprecate exception_install_hook and remove it in a follow
up. It will be replaced with set_interrupt_handler. This way the
exception lookup does not have to manage a list of callbacks, or have to
worry about the order they are processed.
BUG=b:109749762
TEST=Wrote an interrupt handler and fired an APIC timer interrupt and
verified that vector 32 was returned.
