Subject: [PATCH v11 0/9] TI K3 M4F support on AM62 and AM64 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 versions (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

Changes for v11:
 - Added patch [2/9] factoring out a common function
 - Addressed comments by Mathieu from v10
 - Rebased on v6.11-rc1
 - Small reworks in driver for readability

Changes for v10:
 - Rebased on v6.10-rc3
 - Added AM64 M4 support in DT
 - Addressed comments by Mathieu from v9

Changes for v9:
 - Fixed reserved-memory.yaml text in [1/5]
 - Split dts patch into one for SoC and one for board enable
 - Corrected DT property order and formatting [4/5][5/5]
