Hi Vinod,

It looks like you reverted the wrong Kconfig fix, the one I objected to
was the change in drivers/remoteproc, not the one in drivers/dma.

The ST_FMDA depends on functions exposed by REMOTEPROC and
ST_SLIM_REMOTEPROC, the latter in turn depends on REMOTEPROC, which you
guys made user selectable - and as such should not be selected - but I
think we should move forward and get everything merged and then we can
go back and figure out how this should be addressed (or left alone?).

I have merged "topic/st_fdma" into rproc-next, so that I can fix up the
now broken drivers/remoteproc/Kconfig.

We do however both need to revert the revert or there will be link
errors if you build the dma driver with remoteproc=n. If you do this I
can merge the topic once more and we'll keep the set of changes in sync.

Regards,
Bjorn
