2009-08-26ColdFire: Fix compile warning messagesTsiChung Liew
Change %08lX to %08X in board.c. Remove unused variable 'oscillator' in mcf5227x/cpu_init.c and 'scm2' in mcf532x/cpu_init.c. Provide argument type cast in drivers/dma/MCD_dmaApi.c. Signed-off-by: TsiChung Liew <tsicliew@gmail.com>

2009-07-01fsl_dma: Make DMA transactions snoopablePeter Tyser
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.

2009-07-018xxx: Rename dma_xfer() to dmacpy()Peter Tyser
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>
2009-07-01fsl_dma: Fix Channel Start bug in dma_check()Peter Tyser
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>
2009-07-01fsl_dma: Add support for arbitrarily large transfersPeter Tyser
Support DMA transfers larger than the DMA controller's limit of (2 ^ 26 - 1) bytes Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2009-07-018xxx: Break out DMA code to a common filePeter Tyser
DMA support is now enabled via the CONFIG_FSL_DMA define instead of the previous CONFIG_DDR_ECC Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2008-05-21Big white-space cleanup.Wolfgang Denk
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>

MCD_tasks.c lacks [subject] so compilation of mips targets (and more, probably) fails Signed-off-by: Vlad Lungu <vlad@comsys.ro>
