i7core_edac: Memory info fixes and preparation for properly filling cswrow data
Now, memory size is properly displayed: EDAC i7core: DOD Max limits: DIMMS: 2, 1-ranked, 8-banked EDAC i7core: DOD Max rows x colums = 0x4000 x 0x400 EDAC i7core: Memory channel configuration: EDAC i7core: Ch0 phy rd0, wr0 (0x063f7c31): 2 ranks, UDIMMs EDAC i7core: dimm 0 (0x00000288) 1024 Mb offset: 0, numbank: 8, numrank: 1, numrow: 0x4000, numcol: 0x400 EDAC i7core: dimm 1 (0x00001288) 1024 Mb offset: 4, numbank: 8, numrank: 1, numrow: 0x4000, numcol: 0x400 EDAC i7core: Ch1 phy rd1, wr1 (0x063f7c31): 2 ranks, UDIMMs EDAC i7core: dimm 0 (0x00000288) 1024 Mb offset: 0, numbank: 8, numrank: 1, numrow: 0x4000, numcol: 0x400 EDAC i7core: Ch2 phy rd3, wr3 (0x063f7c31): 2 ranks, UDIMMs EDAC i7core: dimm 0 (0x00000288) 1024 Mb offset: 0, numbank: 8, numrank: 1, numrow: 0x4000, numcol: 0x400 Still, as the way to retrieve csrows info is not known, it does a mapping of what's available to csrows basic unit at edac core.
