[coreboot] Doubt about SPD init in Skylake

[王翔]

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 ! ! !
