Subject: [PATCH 0/2] Enable IPU and DSP rprocs on AM5729 BeagleBone AI

Hi Tony, Jason, Caleb,

The IPU and DSP remote processors are finally booting as of latest master
on almost all the TI DRA7xx/AM57xx boards except for AM5729 BeagleBone AI
board. We have most of the common dts pieces available due to the usage
of common dra74-ipu-dsp.common.dtsi and dra7-ipu-dsp-common.dtsi files.
The series leverages these to enable both the IPUs (IPU1 and IPU2) and
DSPs (DSP1 and DSP2) on AM5729 BeagleBone AI board.

Patch 1 is enough to enable the support, and patch 2 is a cleanup.
Patches are based on latest master.

I don't have access to an BeagleBone AI board, so appreciate some testing
from any of you. If you are using the TI SDK firmware images, you would
need the following additional patch [1] to have the rpmsg devices published
successfully (otherwise you will see a malformed rpmsg ns message trace).
This patch is getting replaced with an alternate logic, and I am waiting
for that to be finalized before I update our BIOS-side logic/firmwares.

regards
Suman
