---help---
Support for showing one framebuffer split in 2 displays at the same
time. Each display will show a part of the framebuffer by updating
the corresponding overlay on each display. This feature requires
2 framebuffers so CONFIG_FB_OMAP2_NUM_FBS must be 2 and each
framebuffer must be initialized correctly.
The current implementation supports only panels of the same X and Y
resolutions and both panels must have the same bits per pixel values.
This feature is EXPERIMENTAL and might not be stable if power
management is added at the moment.
It is important to give enough memory to FB0 to allow at least
one buffer with twice the height of a normal single display buffer,
so if the panel needs 864x480x4 bytes for one single display buffer
you must give twice the size which is 864x960x4 with the bootargs
omapfb.vram='0:4M'. To enable double buffering you need to give
864x960x4x2 bytes for two buffers, the bootargs should have
omapfb.vram='0:8M'. Since FB1 must also be initialized properly be
sure to left enough memory for one single buffer (864x480x4 bytes).
The bootarg 'vram' must have the FB0 and FB1 memory requirements
combined. Example:
If you want FB0 with 4M (no double buffering) and FB1 with 2M, the
bootargs must have the following:
vram='6M' omapfb.vram='0:4M,1:2M'
