| ---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' |
