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.

* 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.

This file was being written to the root src directory. It is the only
file being written to src during a normal build, while all others are
being written to $(obj). I added a new variable to allow specifying the
xcompile path. This allows generating a single file if building multiple
boards. I also moved the default location into $(obj) so we don't
pollute the src directory by default.
I also cleaned up the generation of xcompile by removing the unnecessary
eval and NOCOMPILE check.
I also left .xcompile in distclean so it cleans up stale files.
Since .xcompile is written into $(obj), `make clean` will now remove it.
The tegra Makefiles are outside of the normal build process, so I just
updated those Makefiles to point to the default xcompile location of a
normal build. The what-jenkins-does target had to be updated to support
these special targets. We generate an xcompile specifically for these
targets and pass it into the Makefile. Ideally we should get these
targets added to the main build.

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.
