-------

Zen-based AMD systems include a Data Fabric that manages the layout of
10+
physical memory. Devices attached to the Fabric, like memory controllers,
11+
I/O, etc., may not have a complete view of the system physical memory map.
12+
These devices may provide a "normalized", i.e. device physical, address
13+
when reporting memory errors. Normalized addresses must be translated to
14+
a system physical address for the kernel to action on the memory.
15+
16+
AMD Address Translation Library (CONFIG_AMD_ATL) provides translation for
17+
this case.
