- Add Texas Instruments OMAP framebuffer driver. This driver is being used for various OMAP1/2 series based boards and products e.g Nokia N800 Internet Tablet, H4, H3, Siemens SX1 etc. - LCD panel registration and controller code is separated in different file and interfaces.

Say Y here if you want to enable checking if the bootloader has
|
|
already initialized the display controller. In this case the
|
|
driver will skip the initialization.

Increase the DMA consistent memory size according to your video
|
|
memory needs, for example if you want to use multiple planes.
|
|
The size must be 2MB aligned.
|
|
If unsure say 1.

|
|
On systems in which video memory is in system memory
|
|
(SDRAM) this will speed up graphics DMA operations.
|
|
If you have such a system and want to use rotation
|
|
answer yes. Answer no if you have a dedicated video
|
|
memory, or don't use any of the accelerated features.
