Unit tests fail on clang 13.0 because Cmocka's main() function is
declared with return type int, but through some of our chain-include
games it sometimes gets coreboot's main_decl.h which declares the
function as void. Compilers have traditionally always been very
laissez-faire about the signature of the main function, but it seems
that clang has been getting more strict by default recently. Explicitly
disable the related warning to shut it up.

Mock architecture can be used to build libpayload using host compiler.
It can be enabled by setting ARCH_MOCK=y in the dotconfig. It sets
LITTLE_ENDIAN=y, as most machines these days use little-endian CPUs.
Libpayload will use HOSTCC as CC, HOSTLD as LD, etc. instead of tools
provided by xcompile.
Mock architecture configuration can be used by payloads for testing
purposes. Thanks to it, tests can be architecture-independent,
and can be executed without requiring compatible Kconfig options,
e.g. ARCH_ARM64=y for ARM64 machine. However, one has to provide
implementation for most architecture-specific functions present
in arch/* directories.

Currently clear_screen() calls set_pixel() to set all pixels. However,
the actual order of pixels being set depends on the framebuffer
orientation. With NORMAL orientation, the framebuffer is accessed
sequentially; with LEFT_UP/RIGHT_UP orientation, it is accessed back and
forth, leading to performance drop (>1 second on bugzzy).
Therefore, ensure sequential access to the framebuffer, regardless of
the orientation.

- one to remove everything that wasn't our own code, leaving only

- one to copy in Linux 5.13's scripts/kconfig and adapt Makefile.inc
to make the original Makefile work again.
- adapt abuild to use olddefconfig, simplifying matters.
- apply patches in util/kconfig/patches.
- Some more adaptations to the libpayload build system.
The patches are now in util/kconfig/patches/, reverse applying them
should lead to a util/kconfig/ tree that contains exactly the Linux

CB:51638 separated Chrome OS NVS from global NVS by allocating it
separately in CBMEM. CNVS is used in depthcharge to fill firmware
information at boot time. Thus, location of CNVS needs to be shared in
coreboot tables for depthcharge to use.
This change adds a new coreboot table tag
`CB_TAG_ACPI_CNVS`/`CB_TAG_ACPI_CNVS`(0x41) which provides the
location of CNVS in CBMEM to payload (depthcharge).
Additionally, CB:51639 refactored device nvs(DNVS) and moved it to the
end of GNVS instead of the fixed offset 0x1000. DNVS is used on older
Intel platforms like baytrail, braswell and broadwell and depthcharge
fills this at boot time as well. Since DNVS is no longer used on any
new platforms, this information is not passed in coreboot
tables. Instead depthcharge is being updated to use statically defined
offsets for DNVS.
BUG=b:191324611, b:191324611
TEST=Verified that `crossystem fwid` which reads fwid information from
CNVS is reported correctly on brya.

The new `Makefile.payload` can be included by the Makefiles of pay-
loads for in-tree builds. The basic idea is to use libpayload's
build results without the `make install` step, and to ensure that
incremental builds work. For instance, if libpayload's code changes,
a `make` for the payload would automatically update the libpayload
build and rebuild the payload. But if there are no code changes in
libpayload, only updated files of the payload will be re-built.
The configuration of libpayload is supposed to be automatically
generated from a `defconfig` file. If this `defconfig` changes,
libpayload and the payload will be re-built.

We wait up to 5s for the self-test result. On failure or timeout,
the command will be repeated until the 30s init timer runs out. This
happens all in the background of the UI polling loop.
To not unnecessarily delay the boot process, we first try an oppor-
tunistic initialization which skips the self-test.

Move the input-buffer draining into a function. It uses the low-level
i8042 API directly to avoid conflicts with changes in the high-level
keyboard API.

Even if we are careful, it's still possible that we read spurious
data from the keyboard, e.g. keystrokes. Namely, when we send the
reset/disable command, there is a race before the command is pro-
cessed.
So we should always process data from the keyboard in a loop. We
break it, when an ACK (0xfa) or a NAK (0xfe) is received, and warn
on unexpected data unless it might be due to the mentioned race.
This also gives us the opportunity to use command-specific timeouts
which we take from Linux: 1s for the keyboard self-test (as there
are keyboards that perform the test before acking the command) and
200ms for all other commands.
