From a877880c6949e948bd63cd6ea4e216573d2f53dd Mon Sep 17 00:00:00 2001 From: York Sun 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.
