c79cbb5952 x86: dts: Define a default TSC timer frequency
If for some reason, TSC timer frequency cannot be determined from
hardware, nor is it specified in the device tree, U-Boot will panic
resulting in endless reset during boot.

Let's define a default TSC timer frequency using the Kconfig value
CONFIG_X86_TSC_TIMER_FREQ (note: #include must be used instead of
/include/ otherwise the macro is not pre-processed).

54e0bd1728 x86: cros: Check ROM exists before building vboot
All the x86 devicetree files are built at once, whichever board is
actually being built. If coreboot is the target build, CONFIG_ROM_SIZE
is not defined and samus cannot build Chromium OS verified boot. Add
this condition to avoid errors about CONFIG_ROM_SIZE being missing.

80a4570c99 x86: coral: Show memory config and SKU ID on startup
Provide the model information through sysinfo so that it shows up on
boot. For memconfig 4 pins are provided, for 16 combinations. For SKU
ID there are two options:

   - two pins provided in a ternary arrangement, for 9 combinations.
   - reading from the EC

Add a binding doc and drop the unused #defines as well.

Example:

   U-Boot 2021.01-rc5

   CPU:   Intel(R) Celeron(R) CPU N3450 @ 1.10GHz
   DRAM:  3.9 GiB
   MMC:   sdmmc@1b,0: 1, emmc@1c,0: 2
   Video: 1024x768x32 @ b0000000
   Model: Google Coral (memconfig 5, SKU 3)

This depends on the GPIO series:

96d0aa9143 x86: Use CONFIG_CHROMEOS_VBOOT for verified boot
At present CONFIG_CHROMEOS is used to determine whether verified boot is
in use. The code to implement that is not in U-Boot mainline.

However, it is useful to be able to boot a Chromebook in developer mode
in U-Boot mainline without needing the verified boot code.

To allow this, use CONFIG_CHROMEOS_VBOOT to indicate that verified boot
should be used, and CONFIG_CHROMEOS to indicate that the board supports
Chrome OS. That allows us to define CONFIG_CHROMEOS on coral.

With DDR4, Intel SOCs take quite a long time to init their memory. During
this time, if the user is watching, it looks like SPL has hung. Add a

This works by adding a return code to fspm_update_config() that indicates
whether MRC data was found and a new property to the device tree.

Also add one more debug message while starting.

501ba58ae6 x86: coral: Correct some FSP-S settings
Some settings were modified slightly in the device-tree conversion. Return
these to their original values. This includes some audio settings and a
few others that have changed.

Note that we still rely on the FSP defaults for most values, so there is
no need to specify a value if the FSP default is suitable.

This makes WiFi work again.
