This does not happen to have anything to do with the ti,no-reset-on-init
hack for &gpio0 on the am335x-evmsk.dts that's needed to keep DDR
powered? See the am43x thread for more info.

Except for the gpio0 hack..

I got it to the point where some relatively recent u-boot was loading
fine over JTAG but the first stage did not boot properly from NOR for
some reason.
