Hello build bot (Jenkins), Patrick Rudolph,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#3).

Change subject: soc/intel/xeon_sp: Set the MRC "cold boot required" status bit

soc/intel/xeon_sp: Set the MRC "cold boot required" status bit

If bit 0 of byte 0x47 is set FSP will perform full memory training
even if previously saved data is supplied.

Up to and including FSP 2021 WW01 it was reset internally at the end
of PostMemoryInit. Starting with WW03 this is no longer the case and
Intel advised that this bit should be reset externally if valid MRC
data is present.
