[U-Boot] [PATCH 00/11] 85xx/86xx dma updates

[Peter Tyser <ptyser@xes-inc.com>]

This patch series attempts to clean up the DMA implementation for the
85xx and 86xx architectures.  The changes include:
- consolidate 85xx and 86xx structures and code
- add defines for bitfields
- use proper IO accessors
- add support for arbitrarily large transfer sizes
- rename dma_xfer() to dmacpy() and make dmacpy's prototype similar
  to memcpy()

The patches are based on the mainline "next" branch.

I've tested the code on MPC8572 and MPC8640-based boards.

I'm not initimately familar with the 83xx platform, but at a glance
it looked like the fsl_dma driver could be extended to support it
with some ifdeffery.

Peter Tyser (11):
  fsl: Create common fsl_dma.h for 85xx and 86xx cpus
  85xx, 86xx: Sync up DMA code
  85xx, 86xx: Break out DMA code to a common file
  fsl_dma: Add bitfield definitions for common registers
  fsl_dma: Update to use proper I/O accessor functions
  fsl_dma: Add support for arbitrarily large transfers
  fsl_dma: Fix Channel Start bug in dma_check()
  8xxx: Rename dma_xfer() dmacpy()
  fsl_dma: Move dma function prototypes to common header file
  85xx, 86xx: Move dma_init() call to common code
  fsl_dma: Break out common memory initialization function
