We are trying to add a remoteproc driver for a small Cortex M3 called
the WkupM3 used for suspend/resume management on TI AM335/AM437x SoCs.
This processor does not have an MMU. Same is the case with another
processor subsystem PRU-ICSS on AM335/AM437x. All these are platform
devices, and the current iommu_present check will not scale for the same
kernel image to support OMAP4/OMAP5 and AM335/AM437x.

That's perfect, thanks. Can you please add this use case description
to the commit log?

This way we'll be able to recover it easily one day if needed.

Thanks,
Ohad.
