Why do we need a board dependent function for that? We can adjust the setings by storing their value in an environment variable, say some- thing like 800x600...@60hz or copying what Linux does with the "video- mode=" boot argument (we already have drivers/video/videomodes.c). That should be precise enough, and is completely bosrd-independent. > > Boards would start with a (board dependent) default setting, though. > > Yes.

Let's re-use existing interfaces (especially if we then can pass the very same variable as boot argument to Linux).
