My original motivation was that it would only need to be added on
firmwares requiring support for loading into internal memories,
otherwise, these are something left to be managed by the software
running on the remote processor completely, and MPU will not even touch
them.

Sure. But even if you guys will use this interface correctly, this
patch essentially exposes ioremap to user space, which is something we
generally want to avoid.

So, let me know if this is a NAK. If so, we have two options - one to go
the sram node model where each of them have to be defined separately,
and have a specific property in the rproc nodes to be able to get the
gen_pool handles. The other one is simply to define these as <reg> and
use devm_ioremap_resource() (so use DT for defining the regions instead
of a resource table entry).

Any approach where these regions are defined explicitly really sounds
better. If you could look into these two alternatives that would be
great.

OK, will do. Meanwhile, can you pick up Patch 1, that is independent of
this patch.
