[PATCH] omap: dsp: fix for ioremap()

[Felipe Contreras]

Since ioremap() on RAM will be soon disallowed, this is required.

This also requires a patch like:

:)

I thought on just sending the patch, but the last time there wasn't
enough explanation that it depended on another one.

As this code is in CONFIG_TIDSPBRIDGE block and AFAIK that is
not working, this should probably wait for the next merge window?

I plan to send a patch to revert the iommu changes to staging so that
it does work... But this patch would be needed as well.

OK. Let's wait and see what your minimal set of fixes to make it
work looks.

Would it be possible to include this series too (if nothing is
missing)? The only open question was whether to move iva2dsp.h
contents into dsp.h

tidspbridge: SCM layer violation fixes [1]

Patch 4 is to be sent through staging path, once these are pushed.

Regards,

Omar

Huh? Reverting the iommu changes will affect only tidspbridge (staging
tree) the omap codes is not affected at all. I say this patch needs to
be merged regardless.

Anyway, I'm about to send a pull request.
