Generally I was under the impression that this header
double-served as sort of a documentation. I checked
my board and they seem to even use the Arm implementer
ID (instead of their own, as they did in the past),
so I suppose they may be using actual Cortex parts
with no modifications and this patch is not very
beneficial.
