{commonlib/drivers}: Have option to store MRC version inside CBMEM
This patch introduces CBMEM ID to store the MRC version (similar to existing implementation that stores the FSP-M version inside CBMEM ID) inside cbmem so the version information is available across the different coreboot stages. For example: * romstage: Use the CBMEM ID version information to check if the MRC cache is valid and need to erase the MRC cache * ramstage: Use the CBMEM ID to store the MRC cache into the non-volatile space. BUG=b:261689642 TEST=Able to build and boot google/rex and dump the MRC version as below. cbmem --list CBMEM table of contents: NAME ID START LENGTH ... 21. MRC VERSION 5f43524d 75ffeb60 00000004 ... localhost ~ # cbmem -r 5f43524d | hexdump 00000000 01 12 07 00 Signed-off-by: Subrata Banik <subratabanik@google.com> Change-Id: I91f735239b33c6f8ba41c076048903e4b213c6a2 Reviewed-on: https://review.coreboot.org/c/coreboot/+/75921 Reviewed-by: Ronak Kanabar <ronak.kanabar@intel.com> Reviewed-by: Tarun Tuli <taruntuli@google.com> Reviewed-by: Kapil Porwal <kapilporwal@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
