If the raw PM support is built in, we are operating in the split firmware approach mode where RM and PM support is not available. In this case, skip the board config for these two.

We still need to send RM CFG to TIFS in case of J721e in order for DMA to work at R5 SPL. TIFS needs RM CFG to disable firewalls when R5 SPL sends DMA channel cfg requests.
Could you squash the following diff for next version:
Yes, I can squash that in. I believe you have tested this change and it works? (I will obviously double check at my end though.)
Yes, I discovered this when adding DMA support at R5 SPL level on top of current series. Diff is essentially this commit by Dave on TI SDK tree:
