These processors need to use their internal RAM for loading, which is

Ok - so just to make sure I understand, this is physical memory you
want to use, which belongs to the remote processor, and which isn't
mapped normally by the kernel?

Will it suffice to replace the memcpy() with memcpy_toio()?

Yes, memcpy_toio should be fine (and then you don't need to cast the
cookie returned by ioremap).

Thanks,
Ohad.
