[v9,0/5] TI K3 M4F support on AM62 SoCs

Hello all,

This is the continuation of the M4F RProc support series from here[0].
I'm helping out with the upstream task for Hari and so this version(v8)
is a little different than the previous(v7) postings[0]. Most notable
change I've introduced being the patches factoring out common support
from the current K3 R5 and DSP drivers have been dropped. I'd like
to do that re-factor *after* getting this driver in shape, that way
we have 3 similar drivers to factor out from vs trying to make those
changes in parallel with the series adding M4 support.

Anyway, details on our M4F subsystem can be found the
the AM62 TRM in the section on the same:

Thanks,
Andrew
