soc/intel: Fill DIMM serial number from SPD
Fill the DIMM serial number field for SMBIOS from the saved SPD data that is returned by FSP. BUG=b:132970635 TEST=This was tested on sarien to ensure that SMBIOS type 17 filled the serial number from the DIMM: Handle 0x000B, DMI type 17, 40 bytes Memory Device Locator: DIMM-A Serial Number: 41164beb Change-Id: I85438bd1d581095ea3482dcf077a7f3389f1cd47 Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/32853 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Lijian Zhao <lijian.zhao@intel.com>
