[U-Boot] [PATCH v2 00/12] 8xxx dma updates

[Peter Tyser]

This patch series attempts to clean up the DMA implementation for the
83xx, 85xx, and 86xx architectures.  The changes include:
- consolidate 83xx, 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()

Changes since v1:
- Add 83xx patches, these were previously submitted as an RFC
- Add a CONFIG_FSL_DMA check to include/asm-ppc/config.h
- Use phys_addr_t and phys_size_t arguments to dmacpy()

I've tested the code on MPC8572 and MPC8640-based boards.  Ira Snyder
tested on an 83xx-based board.  I compile-tested all 8xxx boards.

Peter Tyser (12):
  85xx, 86xx: Break out DMA code to a common file
  fsl_dma: Add bitfield definitions for common registers
  fsl_dma: Use proper I/O access functions
  fsl_dma: Add support for arbitrarily large transfers
  fsl_dma: Fix Channel Start bug in dma_check()
  8xxx: Rename dma_xfer() to 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
  fsl_dma: Make DMA transactions snoopable
  83xx: Replace CONFIG_ECC_INIT_VIA_DDRC references
  83xx: Add support for fsl_dma driver
