[PATCH v2 00/27] 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

Changes since v1:
- compile tested on MIPS and NIOS
- sync prototypes of the dma_coherent fucntion across all arches
- introduce DMA_ADDRESS_BROKEN in drivers that need fixing for arches
  without 1:1 virt:phys mapping

Regards,
Lucas
