-Files, Configs and Compatibility
-================================
-
-Two files are introduced:
-
- a) 'arch/mips/include/asm/mach-au1x00/au1xxx_ide.h'
- contains : struct _auide_hwif
-
- - timing parameters for PIO mode 0/1/2/3/4
- - timing parameters for MWDMA 0/1/2
-
- b) 'drivers/ide/mips/au1xxx-ide.c'
- contains the functionality of the AU1XXX IDE driver
-
-Following extra configs variables are introduced:
-
- CONFIG_BLK_DEV_IDE_AU1XXX_PIO_DBDMA
- - enable the PIO+DBDMA mode
- CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA
- - enable the MWDMA mode
-
-
-Supported IDE Modes
-===================
-
-The AU1XXX IDE driver supported all PIO modes - PIO mode 0/1/2/3/4 - and all
-MWDMA modes - MWDMA 0/1/2 -. There is no support for SWDMA and UDMA mode.
-
-To change the PIO mode use the program hdparm with option -p, e.g.
-'hdparm -p0 [device]' for PIO mode 0. To enable the MWDMA mode use the option
--X, e.g. 'hdparm -X32 [device]' for MWDMA mode 0.
-
-
-Performance Configurations
-==========================
-
-If the used system doesn't need USB support enable the following kernel
-configs::
-
- CONFIG_IDE=y
- CONFIG_BLK_DEV_IDE=y
- CONFIG_IDE_GENERIC=y
- CONFIG_BLK_DEV_IDEPCI=y
- CONFIG_BLK_DEV_GENERIC=y
- CONFIG_BLK_DEV_IDEDMA_PCI=y
- CONFIG_BLK_DEV_IDE_AU1XXX=y
- CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA=y
- CONFIG_BLK_DEV_IDEDMA=y
-
-Also define 'IDE_AU1XXX_BURSTMODE' in 'drivers/ide/mips/au1xxx-ide.c' to enable
-the burst support on DBDMA controller.
-
-If the used system need the USB support enable the following kernel configs for
-high IDE to USB throughput.
-
-::
-
- CONFIG_IDE_GENERIC=y
- CONFIG_BLK_DEV_IDEPCI=y
- CONFIG_BLK_DEV_GENERIC=y
- CONFIG_BLK_DEV_IDEDMA_PCI=y
- CONFIG_BLK_DEV_IDE_AU1XXX=y
- CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA=y
- CONFIG_BLK_DEV_IDEDMA=y
-
-Also undefine 'IDE_AU1XXX_BURSTMODE' in 'drivers/ide/mips/au1xxx-ide.c' to
-disable the burst support on DBDMA controller.

-These drivers wouldn't have been done without the base of kernel 2.4.x AU1XXX
-IDE driver from AMD.
