The default SPD size is set to 256 bytes, instead of 512 for
LPDDR4/DDR4 if not overridden by the mainboard Kconfig. This caused
the SMBus libraries to read only the lower half of the DIMM SPD on
protectli/vault_ehl. The lower half of the SPD passed to FSP causes
a bug in DIMM change detection, which relies on the CRC of the
manufacturer bytes in the upper half of the SPD (CRC of zero bytes
always gives zero so no change was assumed). Setting the DIMM SPD size
to 512 fixes it.
Setting the SPD size in SoC will also avoid such problems in the future
Elkhart Lake ports. Elkhart Lake supports only LPDDR4/DDR4 so providing
the correct default of 512 bytes is an obvious thing to do.

stepping ID when checking for CPU table entry that matches the silicon
the code is running on. Commit 3ed903fda9 ("soc/intel/xeon_sp/spr: Add
Sapphire Rapids ramstage code") added a CPU table that was missing the
device_match_mask which results in this being 0, so the first entry of
the CPU table would match for any Intel CPU which isn't the intended
behavior. Also use CPU_TABLE_END instead of the final {0, 0, 0} array

Likely all entries could be replaced by one entry that uses the

that's out of scope for this fix.

This patch implements a module that can store the top_of_ram (TOM)
address into non-volatile space (CMOS) during the first boot and
use it across all consecutive boot.
As top_of_ram address is not known until FSP-M has exited, it
results into lacking of MTRR programming to cache the 16 MB TOM,
hence accessing that range during FSP-M and/or late romstage causing
long access times.
Purpose of this driver code is to cache the TOM (with a fixed size of
16MB) for all consecutive boots even before calling into the FSP.
Otherwise, this range remains un-cached until postcar boot stage
updates the MTRR programming. FSP-M and late romstage uses this
uncached TOM range for various purposes (like relocating services
between SPI mapped cached memory to DRAM based uncache memory) hence
having the ability to cache this range beforehand would help to
optimize the boot time (more than 50ms as applicable).

This fixes the case where a Broadwell CPU is combined with an AMD or
NVIDIA GPU would result in using the Broadwell GPU VBIOS file from CBFS
for the discrete GPU too. A further improvement would be to use a list
of the Intel iGPU PCI IDs like it is done in the Skylake code.
TEST=None

On platforms with more than 255 cores the ACPI CPU string
would overflow and generate duplicates. Fix that by changing
the string to hex and use 3 digits.
Test:
Able to boot without ACPI errors on IBM/SBP1 which has
384 actives cores.
