dma: Add i.MX6 support to drivers/dma/apbh_dma.c

2013-04-22T08:26:13+00:00

This will be used by the i.MX6 NAND support.

imx: Move some header files from arch-mxs to imx-common

2013-04-22T08:22:22+00:00

The following headers are moved to a i.MX common location:

- regs-common.h
- regs-apbh.h
- regs-bch.h
- regs-gpmi.h
- dma.h

This way this header can be re-used also by other i.MX platforms.
For example the i.MX6 which will need it for the upcoming NAND
support.

mxs: dma: Fix APBH DMA driver for MX23

2013-01-28T10:43:00+00:00

The MX23 has less channels for the APBH DMA, sligtly different register
layout and some bits in those registers are placed differently. Reflect
this in the driver. This patch fixes MMC/DMA issue on MX23.

MX28: DMA: Prolong the DMA timeout

2012-09-01T12:58:29+00:00

Load from SPI flash can create a long DMA chain, which can take long
time to transfer. Change the DMA timeout to roughly 10s to prevent
such long chains misreporting errors.

mxs: Convert sys_proto.h prefixes to 'mxs'

2012-09-01T12:58:25+00:00

The sys_proto.h functions (except the boot modes) are compatible with
i.MX233 and i.MX28 so we use 'mxs' prefix for its methods.

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.

MXS: Add static annotations to dma driver

2011-12-06T22:59:40+00:00

Some functions were internal to the apbh dma driver, so annotate them static.
Some of the functions weren't used at all so drop them. This makes the U-Boot
binary smaller by about 1500 bytes.

apbh_dma: return error value on timeout

2011-12-06T22:59:40+00:00

When a timeout occurs, the return value is prepared but never returned.
Fix that.
