The system must initialize some arrays before initializing the SPD in order to execute FspMemoryInit.
I do not know what these arrays do, and how do I get these values when porting new motherboard.
These codes exist on the SKYLAKE platform which using FSP2.0. Call path :
fsp_memory_init->do_fsp_memory_init->platform_fsp_memory_init_params_cb->mainboard_memory_init_params
array list :
FSPM_UPD->FspmConfig->DqByteMapCh0
FSPM_UPD->FspmConfig->DqByteMapCh1
FSPM_UPD->FspmConfig->DqsMapCpu2DramCh0
FSPM_UPD->FspmConfig->DqsMapCpu2DramCh1
FSPM_UPD->FspmConfig->RcompResistor
FSPM_UPD->FspmConfig->RcompTarget
If you can help me extremely grateful ! ! !
