i must be out of my tiiiny mind :)  first thoughts: uhh... _that_
ain't gonna be a 4-layer board.

the NAND and LVDS converter ICs are underneath.  NAND actually
*overlaps* (and straddles) both the A13 and the DDR3 RAM.  insane.

the signals from the CPU (mostly DDR3), most of them are going to need
to double-back *underneath* the A13 and then come out using VIAs.

i'm wondering if turning the A13 through 90 degrees would make some of
the signals straighter... RGB/TTL would go straight up (to the LVDS
IC) for a start, and that's 20+ pins...

completely bonkers, and entirely GPLv3.
