[PATCH v7 00/12] x86/edac/amd64: Add support for GPU nodes

[Naveen Krishna Chatradhi]

From: Muralidhara M K <muralimk@xxxxxxx>

On heterogeneous systems made up of AMD CPUs and GPUs, where the
data fabrics of CPUs and GPUs are connected directly via custom links.
UMC MCA banks on GPUs can be viewed similar to the UMCs banks on the CPUs.
Hence, memory errors on GPU UMCs can be reported via edac framework.

This patchset applies on top of the following series
[v4,00/24] AMD MCA Address Translation Updates
https://patchwork.kernel.org/project/linux-edac/cover/20220127204115.384161-1-yazen.ghannam@xxxxxxx/

Each patch was build tested individually. The entire set was
tested for address translation and error counts on GPU
memory.

This patchset does the following
1. edac.rst:
   a. Add Documentation support for heterogeneous systems

2. amd_nb.c:
   a. Add support for northbridges on Aldebaran GPU nodes
   b. export AMD node map details to be used by edac and mce modules
	
3. mce_amd module:
   a. Identify the node ID where the error is and map the node id
      to linux enumerated node id.

4. Modifies the amd64_edac module
   a. Refactor the code, define new family op routines and use
      struct amd64_pvt. Making struct fam_type obsolete.
   b. Enumerate UMCs and HBMs on the GPU nodes

5. DF3.5 Address translation support
   a. Support Data Fabric 3.5 Address translation
   b. Fixed UMC to CS mapping for errors
