* 83xx: Add support for fsl_dma driverPeter Tyser2009-07-02-15/+49

* fsl_dma: Make DMA transactions snoopablePeter Tyser2009-07-01-2/+2
| | | | | | | | | Make DMA transactions snoopable so that CPUs can keep caches up-to-date. This allows dma transactions to be used for operations such as memory copies without any additional cache control operations.

* 8xxx: Rename dma_xfer() to dmacpy()Peter Tyser2009-07-01-1/+1
| | | | | | | | Also update dmacpy()'s argument order to match memcpy's and use phys_addr_t/phy_size_t for address/size arguments Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* fsl_dma: Fix Channel Start bug in dma_check()Peter Tyser2009-07-01-1/+1
| | | | | | | | | | | | The Channel Start (CS) bit in the Mode Register (MR) should actually be cleared as the comment in the code suggests. Previously, CS was being set, not cleared. Assuming normal operation of the DMA engine, this change shouldn't have any real affect. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* fsl_dma: Add support for arbitrarily large transfersPeter Tyser2009-07-01-12/+28

* 8xxx: Break out DMA code to a common filePeter Tyser2009-07-01-0/+93

* Big white-space cleanup.Wolfgang Denk2008-05-21-3/+3
| | | | | | | | | | | This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>
