[LinuxBIOS] What is RC0 and RC1

[Feng, Libo]

The SPD address is composed with RC0, RC1 and DIMM0, DIMM1. But what is RC0 and RC1? Different mainboard has different RC0 and RC1, who defines the two? DIMM sockets or processor or others? Thank you.

Best Regards

We use SMBUS to read/write SPD information. if the mainboard has SMBUS Hub
such as pca9545, you need RC0 and RC1.

That depends on which channel of the SMBUS HUB does your DIMM on.
