At present U-Boot flushes the cache after every character written to ths display. This makes the command-line slower, to the point that pasting in long strings can fail.
Add a cyclic function to sync the display every 10ms. Enable this by default.
Allow much longer times for sandbox, since the SDL display is quite slow.
Avoid size growth if the feature is disabled by making the new init and destroy functions dependent on CYCLIC being enabled.

imply CYCLIC help This enables driver model for LCD and video devices. These support a bitmap display of various sizes and depths which can be drawn onWe should at least expand the help message to say that if you enable cyclic you get some other behavior. In hind sight, cyclic shouldn't be prompted and it should be selected as used. But that's not an issue for this patch set.
Yes it is similar to EVENT I think. But note that some boards do use it for other purposes.
I assume you mean to expand the help for VIDEO
