Ok, but that only makes sense if the monitor is hard-wired to the board itself.
 If a user can attach any monitor he wants, then the EDID data can't be known at
compile time.

I guess it's no different than using hard-coded memory controller programming
instead of SPD.  You can safely avoid SPD only if the DDR chips are soldered on
the board.

It looks like I need to add board-specific EDID reading to the DIU driver.
