The framebuffer layer can be a loadable module, which forces omapfb to be a module as well. However, this breaks the lcd drivers, which are linked into the omapfb driver but each have their own module_init() function. To solve this, we split out the lcd drivers into separate modules and export omapfb_register_panel, which is the only interface required between the main omapfb driver and the lcd panel drivers. We also have to introduce a new Kconfig symbol for H3, since that lcd driver has a dependency on TPS65010, which we can express better in Kconfig than Makefile syntax.

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.
