Actually I had to use ioremap_nocache() call with my ELANSC520 processor (which
has a processor I&D cache).
This is even with caching actually disabled for the flash banks inside the
processor (by the startup processor init code).
Does ioremap() do any caching of it's own? What's the diff between the two?
