When MRC_SAVE_HASH_IN_TPM is selected, mrc_data_valid() uses the TPM
hash to verify the MRC cache data, not the checksum. However, we still
calculate the checksum when updating the cache. Skip this calculation
when MRC_SAVE_HASH_IN_TPM is selected to save boot time.
On nissa, this reduces boot time by ~14 ms:
Before:
3:after RAM initialization 854,298 (28,226)
After:
3:after RAM initialization 849,626 (14,463)
Note, the reason the calculation is so slow is that the new MRC data
lives in CBMEM, which is not yet marked as cacheable in romstage.
BUG=b:242667207
TEST=MRC caching still works as expected on nivviks. After clearing
the MRC cache, memory training happens on the next boot, but doesn't on
subsequent boots.

Clear the SMBIOS region before writing SMBIOS tables.
On librem_mini and librem_mini_v2, CBMEM allocations are offset by 4K
for reboots relative to the cold boot. This means the unused SMBIOS
region could contain the first 4K of the ACPI tables from the last boot
(including the signature), which prevents Linux from booting.
The CBMEM 4K offset appears to be due to FSP allocating memory
differently between cold boot and reboot, this appears to be normal and
causes the CBMEM base address to change.
It is not clear why Linux examines an ACPI signature found in this
region, but boot logs over serial confirm that it sees the corrupt
table. The table is supposed to be found just below 1M, and kernel
source appears to look in this region, but it is definitely finding the
corrupt table in CBMEM.
Normal cold boot:

There are no specific errors but it returns to the firmware soon after,

This patch refactors p2sb_execute_sideband_access() to be able to
handle SBI operations in both SMM and non-SMM scenarios.
Prior to FSP-S operation being done, the IOE P2SB device will be
visible on the PCI bus hence, performing the SBI operation using IOE
P2SB doesn't involve unhide/hide operation.
Post FSP-S, the IOE P2SB device is hidden.
Additionally, SBI operations can't be performed as is. The only
possible way to send SBI is inside SMM mode and to do that, coreboot
needs to unhide the P2SB device prior to sending the SBI and hide
it post sending SBI.
As a result, the p2sb_execute_sideband_access() function has been
refactored to manage these cases seamlessly without users of the
p2sb_execute_sideband_access() actually being bothered about the
calling mode.

Only 16 MByte of the SPI flash can be mapped right below the 4 GB
boundary.
In case of a larger SPI flash size, still only the 16 MByte region
starting at 0xff000000 can be configured as WRPROT and be reserved for
the MMIO mapped SPI flash region. The next 16 MByte MMIO region starting
at address 0xfe000000 contain for example the LAPIC MMIO region, the
ACPIMMIO region and the UART/I2C controller MMIO regions which shouldn't
be configured as WRPROT. Reserving this region for the MMIO mapped SPI
flash would also result in an overlap with the MMIO resources mentioned
above.
In the case of a smaller SPI flash, reserving the full 16 MByte flash
MMIO region makes sure that the resource allocator won't try to put
anything else in the lower parts of the 16 MByte SPI mapping region.
To avoid the issues described above, always reserve/cache the maximum
amount of 16 MBytes of flash that can be mapped below 4 GB.
TEST=On boards with 16 MByte SPI flash chips, the resulting image of a
timeless build doesn't change with this patch. Verified this on Chausie
(Mendocino), Majolica (Cezanne), Cereme (Picasso) and Google/Careena
(Stoneyridge). On Mandolin (Picasso) with an 8 MByte flash, the
resulting image of a timeless build is different, but neither the
coreboot console output nor the Linux dmesg output shows any errors that
might be related to this change.
