From: Muralidhara M K <muralimk@amd.com>

On newer heterogeneous systems from AMD with GPU nodes connected via
xGMI links to the CPUs, the GPU dies are interfaced with HBM2 memory.

This patchset applies on top of the following series by Yazen Ghannam
AMD MCA Address Translation Updates
[https://patchwork.kernel.org/project/linux-edac/list/?series=505989]

This patchset does the following
1. Add support for northbridges on Aldebaran
* x86/amd_nb: Add support for northbridges on Aldebaran
2. Modifies the amd64_edac module to
a. Handle the UMCs on the noncpu nodes,
* EDAC/mce_amd: extract node id from InstanceHi in IPID
b. Enumerate HBM memory and add address translation
* EDAC/amd64: Enumerate memory on noncpu nodes
