Eric Lai b643d3df8a libpayload/drivers/i8042: Add AT translated Keyboard support
Wilco device uses the AT translated keyboard and doesn't need to set
scancode set. Remove the ignore flag and put into translation mode
instead.

BUG=b:145130110
TEST=Draillion keyboard is usable on every boot.

Nico Huber 21bfc9f99b Revert "libpayload: Reset PS/2 keyboard"
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.
This reverts commit 7ae606f57f.

Paul Menzel 7ae606f57f libpayload: Reset PS/2 keyboard
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.

Patrick Georgi 5b2a2d008f src/*: normalize Google copyright headers
As per internal discussion, there's no "ChromiumOS Authors" that's
meaningful outside the Chromium OS project, so change everything to the
contemporary "Google LLC."

While at it, also ensure consistency in the LLC variants (exactly one
trailing period).

"Google Inc" does not need to be touched, so leave them alone.
