+README for MIPS AU1XXX IDE driver - Released 2005-07-15
+
+ABOUT
+-----
+This file describes the 'drivers/ide/mips/au1xxx-ide.c', related files and the
+services they provide.
+
+If you are short in patience and just want to know how to add your hard disc to
+the white or black list, go to the 'ADD NEW HARD DISC TO WHITE OR BLACK LIST'
+section.

+
+
+FILES, CONFIGS AND COMPATABILITY
+--------------------------------
+
+Two files are introduced:
+
+  a) 'include/asm-mips/mach-au1x00/au1xxx_ide.h'
+     containes : struct _auide_hwif
+                 struct drive_list_entry dma_white_list
+                 struct drive_list_entry dma_black_list
+                 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
+
+Four 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
+  CONFIG_BLK_DEV_IDE_AU1XXX_BURSTABLE_ON - set Burstable FIFO in DBDMA
+                                           controler
+  CONFIG_BLK_DEV_IDE_AU1XXX_SEQTS_PER_RQ - maximum transfer size
+                                           per descriptor
+
+If MWDMA is enabled and the connected hard disc is not on the white list, the
+kernel switches to a "safe mwdma mode" at boot time. In this mode the IDE
+performance is substantial slower then in full speed mwdma. In this case
+please add your hard disc to the white list (follow instruction from 'ADD NEW
+HARD DISC TO WHITE OR BLACK LIST' section).
+
+
+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_IDEDMA_PCI_AUTO=y
+CONFIG_BLK_DEV_IDE_AU1XXX=y
+CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA=y
+CONFIG_BLK_DEV_IDE_AU1XXX_BURSTABLE_ON=y
+CONFIG_BLK_DEV_IDE_AU1XXX_SEQTS_PER_RQ=128
+CONFIG_BLK_DEV_IDEDMA=y
+CONFIG_IDEDMA_AUTO=y
+
+If the used system need the USB support enable the following kernel configs for
+high IDE to USB throughput.
+
+CONFIG_BLK_DEV_IDEDISK=y
+CONFIG_IDE_GENERIC=y
+CONFIG_BLK_DEV_IDEPCI=y
+CONFIG_BLK_DEV_GENERIC=y
+CONFIG_BLK_DEV_IDEDMA_PCI=y
+CONFIG_IDEDMA_PCI_AUTO=y
+CONFIG_BLK_DEV_IDE_AU1XXX=y
+CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA=y
+CONFIG_BLK_DEV_IDE_AU1XXX_SEQTS_PER_RQ=128
+CONFIG_BLK_DEV_IDEDMA=y
+CONFIG_IDEDMA_AUTO=y
+
+
+ADD NEW HARD DISC TO WHITE OR BLACK LIST
+----------------------------------------
+
+Step 1 : detect the model name of your hard disc
+
+  a) connect your hard disc to the AU1XXX
+
+  b) boot your kernel and get the hard disc model.
+
+     Example boot log:
+
+     --snipped--
+     Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
+     ide: Assuming 50MHz system bus speed for PIO modes; override with idebus=xx
+     Au1xxx IDE(builtin) configured for MWDMA2
+     Probing IDE interface ide0...
+     hda: Maxtor 6E040L0, ATA DISK drive
+     ide0 at 0xac800000-0xac800007,0xac8001c0 on irq 64
+     hda: max request size: 64KiB
+     hda: 80293248 sectors (41110 MB) w/2048KiB Cache, CHS=65535/16/63, (U)DMA
+     --snipped--
+
+     In this example 'Maxtor 6E040L0'.
+
+Step  2 : edit 'include/asm-mips/mach-au1x00/au1xxx_ide.h'
+
+  Add your hard disc to the dma_white_list or dma_black_list structur.
+
+Step 3 : Recompile the kernel
+
+  Enable MWDMA support in the kernel configuration. Recompile the kernel and
+  reboot.
+
+Step 4 : Tests
+
+  If you have add a hard disc to the white list, please run some stress tests
+  for verification.
+
+
+ACKNOWLEDGMENTS

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