Generally, video drivers request the amount of memory they need for
the frame buffer when they are bound, by setting the size field in
devices to have a framebuffer allocated by U-Boot.
Note: the framebuffer needs to be large enough to store all pixels at
- maximum resolution. For example, at 1920 x 1200 with 32 bits per
+ maximum resolution. For example, at 2560 x 1600 with 32 bits per

+
+ It may also be shorter, since the video uclass will automatically
+ force a sync in certain situations.
