The preferred location for the SPD data on mc_ehl based boards is the HW-Info data structure. Inside this structure there is a field of 128 bytes available for the SPD data. So in order to use it construct a buffer in memory which is 256 bytes long (as FSP requests minimum 256 bytes for the SPD data) and where the upper 128 bytes are taken from HW-Info holding the needed timing parameters for LPDDR4. If there is a case where HW-Info is not accessible or where the contained SPD data is not valid (by checking the CRC in HW-Info SPD) fall back to fixed SPD data set in CBFS.
