S3C2410 DMA
===========
Introduction
------------
The kernel provides an interface to manage DMA transfers
using the DMA channels in the cpu, so that the central
duty of managing channel mappings, and programming the
channel generators is in one place.
DMA Channel Ordering
--------------------
Many of the range do not have connections for the DMA
channels to all sources, which means that some devices
have a restricted number of channels that can be used.
To allow flexibilty for each cpu type and board, the
dma code can be given an dma ordering structure which
allows the order of channel search to be specified, as
well as allowing the prohibition of certain claims.
struct s3c24xx_dma_order has a list of channels, and
each channel within has a slot for a list of dma
channel numbers. The slots are searched in order, for
the presence of a dma channel number with DMA_CH_VALID
orred in.
If the order has the flag DMA_CH_NEVER set, then after
checking the channel list, the system will return no
found channel, thus denying the request.
A board support file can call s3c24xx_dma_order_set()
to register an complete ordering set. The routine will
copy the data, so the original can be discared with
__initdata.

The Samsung S3C24XX range of ARM9 System-on-Chip CPUs are supported
by the 's3c2410' architecture of ARM Linux. Currently the S3C2410,
S3C2440 and S3C2442 devices are supported.
S3C2412, S3C2413, S3C2440 and S3C2442 devices are supported.
Support for the S3C2400 series is in progress.
Support for the S3C2412 and S3C2413 CPUs is being merged.
Configuration

......@@ -26,6 +23,22 @@ Configuration
please check the machine specific documentation.
Layout
------
The core support files are located in the platform code contained in
arch/arm/plat-s3c24xx with headers in include/asm-arm/plat-s3c24xx.
This directory should be kept to items shared between the platform
code (arch/arm/plat-s3c24xx) and the arch/arm/mach-s3c24* code.
Each cpu has a directory with the support files for it, and the
machines that carry the device. For example S3C2410 is contained
in arch/arm/mach-s3c2410 and S3C2440 in arch/arm/mach-s3c2440
Register, kernel and platform data definitions are held in the
include/asm-arm/arch-s3c2410 directory.
