-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

- 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.
