Date: Mon, 29 Oct 2007 13:58:39 -0500 Subject: 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.

Add cfb console support to FSL 8610 DIU driver. Inspect board version from PIXIS to obtain correct pixel format. Use #define CONFIG_VIDEO in config file to enable fb console. To switch monitor, set monitor variable to 0 - DVI, 1 - Single link LVDS, 2 - Double link LVDS followed by "diufb init". Preserve logo bitmap at the top of the fb console.
