This is a initial mainboard code cloned entirely from jasperlake_rvp
aimed to serve as base for further mainboard check-ins.
This patch is based on TGL_upstream series patches:
https://review.coreboot.org/c/coreboot/+/37868
List of changes on top off initial jasperlake_rvp clone:
1. Replace "Jasperlake" with "Elkhartlake"
2. Replace "jsl" with "ehl"
3. Replace "jslrvp" with "ehlcrb"
4. Remove unwanted SPD file, add empty SPD as placeholder
6. Empty romstage_fsp_params.c, to fill it later with SOC specific
config
7. Empty GPIO configurations, to be filled as per board
8. Empty memory.c configurations, to be filled as per board
9. Add board support namely BOARD_INTEL_ELKHARTLAKE_CRB
10. Replace jslrvp variant with ehlcrb variant
Changes to follow on top of this:
1. Add correct memory parameters, add SPDs
2. Clean up devicetree as per tigerlake SOC
3. Add GPIO support
4. Update ehl fmd file to replace 32MB chromeos.fmd

mtk_init_mcu uses DRAM_DMA section as CBFS buffer.
The change "mediatek/mt8183: Remove DRAM_DMA section" is reverted
for using mtk_init_mcu.
On mt8173 and mt8192, this region is used by DMA hardware and is
marked as non-cacheable resource. On mt8183, this region is reserved
as CBFS buffer, so it is not necessary to be marked as non-cacheable

The pads have been determined by dissecting a dead board. This commit
only changes pads, that are not connected at all and don't have any via,

(Re)configure various pads found by dissecting a dead board and vendor
firmware, as well as the BMC firmware:
- GPP_B14: input connected to jumper JBR1 - could be used to implement
"BIOS Recovery" ("Top-Block Swap") functionality; external pull-up
- GPP_C20: output to BMC alert CPU_THROTTLED# - can be used to notify
the BMC about a thermal throttling event. Not implemented in vendor
firmware.
- GPP_C23: input connected to the CPU's CATERR# output; external pull-up
Not actively used by vendor firmware.
- GPP_D1: output connected to on-board and front panel power LEDs
- GPP_D18: output connected to PERST# of both CPU PCIe Slots. Can be
used for testing/debugging only, since it resets both slots at once.
Not actively used by vendor firmware.
- GPP_D19: output connected to PERST# of both PCH PCIe Slots. Can be
used for testing/debugging only, since it resets both slots at once.
Not actively used by vendor firmware.
- GPP_D22: input connected to the BMC enable/disable jumper JPB1; Will
be used later in CB:48096 and CB:48097; external pull-up
- GPP_G0 - GPP_G3: dedicated/integrated CPU switching; probably not
useful, since the IGD is not connected to any ports on this board.
External pulls ensure correct function of a dGPU even without driving
the gpios. Not used by vendor firmware.
- GPP_G12 - GPP_G16: inputs for binary SKU_ID; external pulls
- GPP_G20: PWRFAIL# input from JPI2C1 (pin 3); external pull-up; Not
used by vendor firmware.
Also add comments for documentation. While at it, mark ME-owned pads as

This patch addresses the same problem as CB:48429, but hopefully this
time correctly. Since the mcache is not guaranteed to be available on
the first CBFS lookup for some special cases, we can no longer treat it
as a one-time fire-and-forget initialization. Instead, we test
cbd->mcache_size to check if the mcache has been initialized yet, and
keep trying on every lookup if we don't find it the first time.
Since the mcache is a hard requirement for TOCTOU safety, also make it
more clear in Kconfig that configurations known to do CBFS accesses
before CBMEM init are incompatbile with that, and make sure we die()
rather than do something unsafe if there's a case that Kconfig didn't
catch.

This change reorganizes FMAP for volteer to make use of the lower
16MiB of the SPI flash for RW_SECTION_A and RW_MISC in addition to
RW_LEGACY. This is now possible because TGL supports memory mapping of
BIOS region greater than 16MiB.
Following changes are made in chromeos.fmd as part of this:
1. Move RW_SECTION_A and RW_MISC to lower 16MiB.
2. Reduce size of RW_LEGACY to 2MiB since we longer need to use it as
a placeholder in the lower half of the SPI flash.
3. Reduce size of RW_ELOG to 4KiB as coreboot does not support a
larger region for ELOG.
4. Increase WP_RO to 8MiB to allow larger space for firmware
screens. GBB size is thus increased to 448KiB.
