[PATCH 00/24] Phasing out direct usage of asm/mmu.h on ARM

[Lucas Stach]

This series introduces to Barebox the streaming DMA ops and implements
them for the ARM architecture. This will make it a lot easier to
get common cache maintenance operations for all architectures and in
turn allows for wider reuse of driver across architectures.

I've tested this on a Tegra124 which is known to fall over in all sorts
of funny ways if cache maintenance is broken. No odd behavior spotted.

The series is bisect-clean and I've compile tested it on some defconfigs,
but please go wild and TEST. I'll take any complaints.

Changes since RFT:
- rebased to current master
- now compile tested on all ARM defconfigs
- fixed a few compile errors by reordering stuff in patches
- A few more words in commit logs

Regards,
Lucas
