elog_gsmi_cb_mainboard_log_wake_source is called from SMI and causes
eSPI transactions. If the SMI interrupts an ongoing eSPI transaction
from the OS it will conflict and cause failures. Removing this call to
avoid conflicts. This can be re-enabled after refactoring
google_chromeec_get_mask to use ACPI MMIO.

Since Sabrina uses the image slot header (ISH) that depends on the AMD
A/B recovery scheme that depends on the multi-level PSP directory
support, the multi-level support gets automatically selected by passing
Sabrina as SoC name to amdfwtool, so passing the --multilevel command
line switch to amdfwtool isn't needed.

The fch_i23c_pad_init implementation was written without looking at any
reference code and turned out to not work properly on hardware. Before
this function writes to the MISC_I23C_PAD_CTRL registers, the value read
back is 0x3000003c which results in the I2C bus communication to work
while the 0x300003fc the code writes to the register breaks the I2C
communication. Removing the code that sets bits 6..9 fixes the I2C bus
communication.

Contradicting the PPR #57243 version 1.56, the I2C3 pad control register
in the MISC ACPIMMIO region is the same new I23C pad type as the
corresponding registers for I2C0..2 and not the older I2C pad control
register type used on Picasso and Cezanne. All I2C pads being of the new
I23C type is in line with the GPIOMUX settings for the pins used by
I2C0..3 that can alternatively connect the pins to an I3C controller.

We set T3 as 300ms to meet Elan's spec, but the resume/suspend times
are greater than 500ms, which is the spec for Chromebooks.
The actual kernel timing has been measured, and given the ACPI delay
after deasserting reset in addition to the delay until the kernel
driver accesses the device, delaying only 200ms in the ACPI method is
also sufficient to meet the 300ms requirement.

Add new board Clevo L14xMU (TGL).
GPIOs were configured based on schematics.
Tested and working:
- On-board RAM (M471A1G44AB0-CWE)
- DIMM slot (tested Crucial CT16G4SFD8266.16FJ1 / MTA16ATF2G64HZ-2G6J1)
- Graphics (GOP driver), including HDMI
- Keyboard
- I2C touchpad (including interrupt)
- TPM (with interrupt on Windows, only polling on Linux [1])
- microSD Card reader
- both NVME ports
- Speakers
- Microphone
- Camera
- WLAN/BT (CNVi)
- All USB2/3 ports including Type-C
- Thunderbolt detects my work laptop in TB Control Center
(I couldn't test anything more due to security policy.)
- TianoCore
- internal flashing with flashrom on vendor firmware
Note on TPM:
The vendor sets Intel PTT to default-on in newer CSME images, which
conflicts with the dTPM. Currently, there are two ways to make it work:
1) Boot vendor firmware once to let it disable PTT via CSME firmware
feature override.
2) Use Intel Flash Image Tool (FIT) to set "initial power-up state" to
disabled.
Boots fine:
- Debian testing, unstable (Linux 5.16.14, 5.17.0-rc6)
- Windows 10 21H2 (Build 19044.1586)
Untested:
- Thunderbolt (see above)
- Type-C DisplayPort
- S-ATA
Doesn't work:
- TPM interrupt on Linux [1]
- All EC related functions - EC driver is WIP
- WLAN/BT (PCIe) - gets detected but can't be enabled
- 3G/LTE (not powered without EC driver)
- Fn-Keys
- S0ix
- UCSI
- Fan control
- Battery info

When rebuilding coreboot the empty fit table added to added to CBFS
stays the same so the build process sees no reason to update the file.
In the meantime ifittool did update that file for instance to add
microcode update entries. So each time coreboot is rebuilt the entries
are appended to the FIT table which runs out of space at some point.
One way to deal with this is to clear the fit table when setting the
pointer inside the bootblock.
TESTED: Now running 'make' again on prodrive/hermes does not report an
error with a filled FIT table.

SoC name parameter passed to amdfwtool from Cezanne to Sabrina.
The fw.cfg file still points to the Cezanne binaries, but since
commit 9cb0a05dfb (soc/amd/sabrina: Add
prompt for AMDFW_CONFIG_FILE) this can be overridden via the Kconfig
config file in the build. As soon as the Sabrina PSP binaries are
available in 3rparty/amd_blobs, the fw.cfg file will be updated to use
the correct ones for Sabrina.
