The big issue is the SPL. Right now I'm using Rockchip's ddr-init as spl-
replacement, and I'd say this second part is nearly ready - only minor 
cleanups.

The memory-setup is supposed to be very much similar to the rk3288 (same 
dw_upctl and ddr-phy), but it looks like the very first steps are somewhat 
different and I haven't been able to make the spl output anything on the 
serial console yet ... which could stem from some difference in what the soc 
expects or just some dumb mistake on my part :-)
