This patch adds a new way of implementing flash access for libpayload.
Until now all reads had to be performed using cbfs_media, which is
obsolete. From now on all reads should be performed using
boot_device_read().
This patch also provides a default implementation of boot_device_read()
for x86 architecture.

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.

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 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.

The keyboard self-test is required for some devices. At least one
device (integrated keyboard in a ThinkPad X201) actually starts the
test automatically leading to spurious output and no response for
the first seconds.
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.

We'll process the init sequence as part of the polling loop. This

* It eases error handling, i.e. we can return to an earlier state.
* We don't have to stall initialization when a keyboard takes a

* Generally, these keyboards can be hot-plugged (albeit not by

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.

Some background first: The original XT keyboards used what we call
scancode set #1 today. The PC/AT keyboards introduced scancode set #2,
but for compatibility, its controller translated scancodes back to
set #1 by default. Newer keyboards (maybe all we have to deal with)
also support switching the scancode set.
This means the translation option in the controller and the scancode
set selection in the keyboard have to match. In libpayload, we only
support set #1 scancodes. So we either need the controller's trans-
lation on and set #2 selected in the keyboard, or the controller's
translation off and set #1 selected in the keyboard.
Valid configurations:
* SET #1 + XLATE off
* SET #2 + XLATE on
Both with and without the PC_KEYBOARD_AT_TRANSLATED option, we were
only configuring one of the two settings, leaving room for invalid
configurations. With this change, we try to select scancode set #2
first, which seems to be the most supported one, and configure the
controller's translation accordingly. We try to fall back to set #1
on failure.
We also keep translation disabled during configuration steps to
ensure that the controller doesn't accidentally translate confi-
guration data.
On the coreboot side, we leave the controller's translation at its
default setting, unless DRIVERS_PS2_KEYBOARD is enabled. The latter
enables the translation unconditionally. For QEMU this means that
the option effectively toggles the translation, as QEMU's controller
has it disabled by default. This probably made a lot of earlier
testing inconsistent.
Fixes: commit a95a6bf646 (libpayload/drivers/i8402/kbd: Fix qemu)
The reset introduced there effectively reverted the scancode
selection made before (because 2 is the default). It's unclear
if later changes to the code were only necessary to work
around it.

This change adds details about the memory map windows to translate
addresses between SPI flash space and host address space to coreboot
tables. This is useful for payloads to setup the translation using the
decode windows already known to coreboot. Until now, there was a
single decode window at the top of 4G used by all x86
platforms. However, going forward, platforms might support more decode
windows and hence in order to avoid duplication in payloads this
information is filled in coreboot tables.
`lb_spi_flash()` is updated to fill in the details about these windows
by making a call to `spi_flash_get_mmap_windows()` which is
implemented by the driver providing the boot media mapping device.

Link time optimization is a technique for whole-program optimization.
Instead of doing code generation during compilation, the compiler saves
its intermediate representation to the object files. During the final
linking step, it will then merge all the object files together and
perform optimizations on the entire program. This can often reduce the
final binary size, but also may increase the total compilation time.
This patch introduces a Kconfig option for enabling link time
optimization in libpayload. Since libpayload does no linking of its own,
its LTO archive files will contain only IR and no generated code.
Downstream projects will need to use LTO-aware tools when manipulating
the archives (eg. gcc-ar and gcc-nm), but otherwise do not need to use
LTO themselves -- the compiler will recognize which files are LTO and
which are not, so enabling this option should mostly be "drop in".
For example, when building coreinfo.elf using tinycurses libpayload:
binary size compilation time
default 114 KiB 11.49s
LTO 95 KiB 10.36s
In this case the total compilation time was actually shorter -- despite
the final linking step taking longer, this was offset by the shorter
compilation times for each individual file (since there is no code gen
until the very end).

SMMSTORE version 2 is a complete redesign of the current driver. It is
not backwards-compatible with version 1, and only one version can be

Key features:
* Uses a fixed communication buffer instead of writing to arbitrary
memory addresses provided by untrusted ring0 code.
* Gives the caller full control over the used data format.
* Splits the store into smaller chunks to allow fault tolerant updates.
* Doesn't provide feedback about the actual read/written bytes, just
returns error or success in registers.
* Returns an error if the requested operation would overflow the
communication buffer.
Separate the SMMSTORE into 64 KiB blocks that can individually be
read/written/erased. To be used by payloads that implement a
FaultTolerant Variable store like TianoCore.
The implementation has been tested against EDK2 master.

The current initialization of the 'equals' counter is incorrect, so that
when 'equals >= SSZ * SSZ', the pixels in the sample array might not be
all the same, leading to a wrong pixel value being set in the
framebuffer.
The 'equals' counter stores the number of latest pixels that were
exactly equal. Within the for loop of 'ox', the sample array is updated
in a column-based order, and the 'equals' counter is updated
accordingly. However, the 'equals' counter is initialized in a row-based
order, which causes it to be set too large than it should be. Consider
the example where sample[sx][sy] are initially:
[X X X A A A] // sy = 0
[X X X B B B]
[X X X B B B]
[X X X B B B]
[X X X B B B]
[X X X B B B] // sy = SSZ
Then, the correct implementation will initialize 'equals' to be 15, with
last_equal being B. Suppose all of the remaining pixels are B. Then, at
the end of the 'while (fpfloor(ixfp) > ix)' loop when ix = 4, or
equivalently after 4 more columns of sample are updated, 'equals' will
be 15 + 6 * 4 = 39, which is greater than SSZ * SSZ = 36, but we can see
there are still 2 A's in the sample:
[B B B B A A]
[B B B B B B]
[B B B B B B]
[B B B B B B]
[B B B B B B]
[B B B B B B]
Therefore, we must also initialize the 'equals' counter in a
column-based order.

The current realloc() works by freeing the origin buffer, allocating a
new one, and copying the data over. It's true that free() won't touch
the actual memory. However, the alloc() following it will potentially
modify the memory that belongs to the old buffer in order to create a
new free block (right after the newly allocated block). This causes 8
bytes (HDRSIZE) to be overwritten before being copied to the new buffer.
To fix the problem, we must create the header of the new free block
after the data is copied. In this patch, the content of alloc() is split
into two functions:
1. find_free_block(): Find a free block with large enough size, without
touching the memory
2. use_block(): Update the header of the newly allocated block, and

We do not need to set the CS (Command Stop) bit in the Command Ring
Control Register. CS is implied by CA (Command Abort). I'm not sure if
there is a defined execution order for these command bits, so it's
safer to only use the CA bit as it includes the CS function.

This fixes issues with how we handle events generated by the xHCI
"command abort" command. first, depending on the state of the xHCI
controller, the COMMAND_ABORTED may not be generated. If the
controller was between commands, only the COMMAND_RING_STOPPED event
will be generated. Second, do not adjust the command ring "cur"
pointer as that just confuses the controller.

For payloads with UI based on CBGFX, they usually start by calling
clear_canvas or clear_screen and then draw the UI elements. However,
that makes the screen flicker.
A typical solution is to identify and minimize the area to redraw.
However for payloads with complicated UI and do not care about latency,
an alternative is to enable buffered I/O.
The new enable_graphics_buffer() will redirect all graphics I/O
into an invisible working buffer. To flush (redraw) the buffer to the
real screen, call flush_graphics_buffer(). To stop buffering, call
disable_graphics_buffer().
BUG=None
TEST=Add the enable, flush and disable calls to payload 'depthcharge',
built a firmware and boots into Chrome OS recover UI. No more
flickering. The average rendering time on x86 platform is 1.2ms.
