DMA: Split the APBH DMA init into block and channel init

2012-04-16T12:53:59+00:00

This fixes the issue where mxs_dma_init() was called either twice or never,
without introducing any new init hooks.

The idea is to allow each and every device using the APBH DMA block to
configure and request only the channels it uses, instead of making it call init
for all the channels as is now.

The common DMA block init part, which only configures the block, is then called
from CPUs arch_cpu_init() call.

i.MX28: Allow coexistence of PIO and DMA mode for SD/MMC

2012-04-16T12:53:59+00:00

This SD DMA function of i.MX28 is still apparently too experimental to be
enabled by default in 2012.04 release. Enable this feature only if the user
plans to tinker with DCache or explicitly enables it.

i.MX28: Do data transfers via DMA in MMC driver

2012-03-29T05:56:42+00:00

This utilizes the newly introduced bounce buffers in the MMC layer.

MMC: Implement generic bounce buffer

2012-03-29T05:56:39+00:00

This implements generic bounce buffer at the end of MMC command submission
chain. Therefore if unaligned data are passed, they are copied. This stuff
should be pushed down into the MMC subsystem to squash all places generating
these unaligned data.

ATMEL: remove old atmel_mci driver

2012-03-13T11:06:42+00:00

All boards are using the gen_atmel_mci driver now, so no need
to carry the old driver around.

ATMEL: use generic mmc framework

2012-03-13T11:06:41+00:00

gen_atmel_mci works on AVR32 as well, so no need to use the legacy
mmc driver. This also has the nice side effect of being able to use
SDHC cards an those boards.

mmc: make mmc_send_status() more reliable

2012-02-15T23:42:22+00:00

Align the card status polling with the Linux kernel and retry the
command at least five times. Also some cards apparently mishandle the
status bits, so make sure to check the card state too.
