8610: Add 8610 DIU display driver
1280x1024 and 1024x768 @ 32 bpp are supported now.
DVI, Single-link LVDS, Double-link LVDS are all supported.
Environmental variable "monitor" is used to specify monitor port.
A new command "diufb" is introduced to reinitialize monitor
and display a BMP file in the memory. So far, 1-bit, 4-bit,
8-bit and 24-bit BMP formats are supported.
diufb init
- initialize the diu driver
Enable the port specified in the environmental variable "monitor"
diufb addr
- display bmp file in memory.
The bmp image should be no bigger than the resolution, 1280x1024
for DVI and double-link LVDS, 1024x768 for single-link LVDS.
Note, this driver allocate memory but doesn't free it after use
It is written on purpose -- to avoid a failure of reallocation
due to memory fragement.
ECC of DDR is disabled for DIU performance. L2 data cache is also disabled.
