This change adds type-c port information for USB Type-C ports to the

Yu-Ping Wu 52889c9c9f libpayload: cbgfx: Clear screen by sequential access
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.

Patrick Georgi 53ea1d44f0 util/kconfig: Uprev to Linux 5.13's kconfig
This was originally several commits that had to be squashed into one
because the intermediate states weren't able to build coreboot:

 - one to remove everything that wasn't our own code, leaving only
   regex.[ch], toada.c, description.md and Makefile.inc.
 - 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
version + our own 5 files.

Furquan Shaikh bda86bd497 nvs: Add Chrome OS NVS (CNVS) information to coreboot tables
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.

If we select scancode set #1 and keep that, it can confuse Linux
with keyboards that don't return to set #2 when asked to load the
defaults. This happens for instance with various integrated Think-
Pad keyboards but was also seen with an external PS/2 one.

The chosen configuration, scancode set #2 without translation, seems
to be the default for many systems. So we can expect other payloads
and kernels to work with it.

Nico Huber 9c8f0424d6 libpayload: Add a Makefile for in-tree payloads
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.

Nico Huber 9d233ba9a9 libpayload/lpgcc: Check for `libpayload.config` for in-tree builds
Instead of checking for an already fully build `libpayload.a`, we check
for the `libpayload.config` which is the actual prerequisite to start
using `lpgcc`. This will allow compilation of payload sources before or
in parallel with the build of `libpayload.a`.

Nico Huber e9c572f203 libpayload/keyboard: Implement self-test
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

Nico Huber a160d93dda libpayload/keyboard: Revise keyboard_cmd() error handling
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.

Nico Huber a69d682a0b libpayload/keyboard: Revise scancode set and translation config
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.

Furquan Shaikh 493937e1d6 coreboot tables: Add SPI flash memory map windows to coreboot tables
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.
