Commit 3ba6f8cdf (drivers/intel/fsp2_0: Add native implementation for
FSP Debug Handler) implements a native FSP debug handler.
However, coreboot still can't control when to redirect FSP debug
output to the serial console, i.e., at present, integrating a FSP debug
binary is enough to output FSP serial messages irrespective of whether
user is intended to see FSP debug log.
coreboot needs additional mechanism to control FSP debug binary to
redirect debug messages over serial port. This patch introduces a
config `FSP_ENABLE_SERIAL_DEBUG` to control the FSP debug output, user
to enable this config from site-local config file in case like to override
the default FSP serial redirection behaviour in more controlled way from
coreboot.
There could be scenarios as below:
Scenario 1: coreboot release image integrated with the FSP debug
binaries, is capable of redirecting to the serial console, but coreboot
decides to override the config as below to skip FSP debug output
redirection to the serial port.
`#`FSP Serial console disabled by default (do not remove)
`#`CONFIG_FSP_ENABLE_SERIAL_DEBUG is not set
Scenario 2: For coreboot serial image with FSP debug binaries integrated
but coreboot decides to skip FSP debug output redirection to the serial
port.
`#`FSP Serial console disabled by default (do not remove)
`#`CONFIG_FSP_ENABLE_SERIAL_DEBUG is not set
CONFIG_CONSOLE_SERIAL=y
CONFIG_CONSOLE_SERIAL_115200=y
CONFIG_UART_DEBUG=y
CONFIG_UART_FOR_CONSOLE=0
Scenario 3: The final image could be a coreboot serial image with FSP
serial redirection enabled to output to the serial port.
CONFIG_FSP_ENABLE_SERIAL_DEBUG=y
CONFIG_CONSOLE_SERIAL=y
CONFIG_CONSOLE_SERIAL_115200=y
CONFIG_UART_DEBUG=y
CONFIG_UART_FOR_CONSOLE=0

Commit 1a4496e79f (soc/{apl,glk}: Allow to select the primary graphics
device) adds code to set the FSP parameter 'PrimaryVideoAdaptor' based
on the enum description of the FspmUpd.h for Apollo Lake.
Unfortunately, the comment in the header file does not match the
implementation in the FSP and hence setting PrimaryVideoAdaptor to
'GPU_PRIMARY_IGD' will be treated as if the selection was
'GPU_PRIMARY_PCI'. This in turn leads to Linux gfx driver issues for
earlier driver implementations.
This commit corrects the enum values for the FSP parameter to match the
implementation.
TEST=Boot into Linux on mc_apl1 and verify that graphics works.

Some bytes in the descriptor need to be set differently for Type-C and
HDMI. To allow using a single firmware variant for both cases, update
the descriptor at runtime based on fw_config. This is a temporary
workaround while we find a better solution.
The byte values were determined by changing the following CSE strap and
comparing the generated descriptors:
Type-C: TypeCPort2Config = "No Thunderbolt"
HDMI: TypeCPort2Config = "DP Fixed Connection"
The default value before updating the descriptor is Type-C, but this was
chosen arbitrarily.
BUG=b:226848617
TEST=Type-C and HDMI both work on nereid with fw_config set correctly.

On nereid, we need to update the descriptor based on fw_config (see
the follow-up patch), so add support to update the descriptor at
runtime. This is a temporary workaround while we find a better solution.
This is basically adding back the configure_pmc_descriptor() function
removed in CB:63339, just making it generic and allowing it to update
multiple bytes at once.
BUG=b:226848617
TEST=With the following patch, Type-C and HDMI work on nereid.

The patch removes Kconfig CONFIG_ALDERLAKE_A0_CONFIGURE_PMC_DESCRIPTOR
code which updates PMC descriptor for an intermediate ADL-P SoC
stepping A0. Since intermediate ADL-P SoC is no longer supported and no
board is selecting the Kconfig, so remove the code that updates PMC
descriptor.
TEST=Build and boot Gimble board

The symbol watchdog_tombstone is not really about ChromeOS
but ELOG instead. This prepares for furher move of the
