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).

Also undefine 'IDE_AU1XXX_BURSTMODE' in 'drivers/ide/mips/au1xxx-ide.c' to
disable the burst support on DBDMA controller.
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: 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.
