Hi Ohad,

The following is an updated patchset addressing the previous pending comments
from v1 & v2, and are rebased onto the latest 3.19-rc3 (are rc independent
actually). 

The patches are mainly developed to support the WkupM3 remote processor driver
on TI AM335x/AM437x SoCs, and I have verified the loading using the latest
version of Dave's WkupM3 remoteproc work [1]

The only change in v3 is on the second patch, it mainly leverages the
memcpy_toio and memset_io functions for copying/loading code into the
internal memory sections. An additional argument has to be added to the
rproc_da_to_va function to make this distinction.

regards
Suman
