Probably the frame buffer memory allocation did not work.
Could you please try with a bind callback, i.e.:
static int rx51_video_bind(struct udevice *dev)
{
struct video_uc_plat *plat = dev_get_uclass_plat(dev);
plat->size = 800 * 480 * 2;
return 0;
}
...
U_BOOT_DRIVER(rx51_video) = {
.name = "rx51_video",
.id = UCLASS_VIDEO,
.bind = rx51_video_bind,
.probe = rx51_video_probe,
.flags = DM_FLAG_PRE_RELOC,
};

Not yet. There were some logo related changes recently, but if I
remember correctly, I tested them on wandboard and nitrogen6q
targets and with sandbox, and logo drawing worked there.
