Subject[PATCH v3 10/31] i7300_edac: Convert it to report memory with the new location
Date
On this driver, the memory controller supports only FB-DIMMs.

The memory controller hierarchy here has 3 layers bellow the
memory controller:
- two branches;
- each branch has two channels;
- each channel can select up to 8 DIMM's via the
FB-DIMM AMB (Advanced Memory Buffer) chip.

As EDAC currently limits memory controllers to 2 hierarchy
levels, on this patch, both branches and channels are grouped
together.
