I have only tested on AM180x with uio_pruss and davinci-pcm (series
for that posted a short while ago). In the uio_pruss case, I run the
sample applications from the userspace PRU package that test
communication with the shared SRAM, DDR, and internal PRU SRAM. For
davinci-pcm, my series enables shared SRAM ping-pong buffering which is
working comparably to pcm capture/playback without ping-pong buffering
enabled on AM180x.

I have not tested PM at all...yet.

I'll add this detail to the commit.
