-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.
