[PATCH 00/13] pxa3xx patches to support mvebu builds

[Ezequiel Garcia]

Hello everyone!

This patchset is part of the work I'm doing to enable the pxa3xx-nand
driver to support the NAND controller in Armada 370/XP. While this
work in progress, here's a subet of patches I consider good enough
for mainline.

It's worth noting that using these patches and adding appropriate
DT nodes, the NAND controller in Armada 370/XP SoC can detect
devices that are ONFI-compliant.

It's also worth noting that since pxa3xx has a mach-specific
DMA API, I'm including a few patches to ifdef such pxa-specific
code in non PXA/MMP platforms. This ugly workaround should be
removed once the specific DMA API is replaced by dmaengine.

Since there's no current schedule on when should that move happen,
for now we have no choice but to implement some ifdefs workaround.

Other than that, the rest of the patchset is just assorted cleanups
and minor fixes.

I'm Ccing some past pxa3xx-nand testers and reviewers, with the hope
they can take a look at this new patchset.

Any feedback and testing will be highly appreciated!
