BTW, I tested out our your branch, but I think I'm missing a step as where to put the SPL DTB?

Do:
make u-boot-with-spl-dtb.sfp
Does your updated branch still work for you on the SoCKit? I'm hitting the dreaded "CALIBRATION FAILED" on all my boards here, the devkit, SoCKit and the new Atlas SoCKit.

Hi!
You probably need the use different DRAM config for the sockit (I do use different ones, generated from Quartus). I pushed my SoCkit hacks to [1] (u-boot-socfpga / vip/sockit). This is tested last time today, so it should work for you.
Also, notice the topmost patch [2]. You can ignore (and drop) the delay in spl.c , that's a hack I use to make it wait until my USB catches up after cold reset of the sockit. The change to timer.c is something that's baffling me -- without this change I also get calibration failure, but I didn't find out why yet.
To make it ever weirder, if I use gcc 5.0.x , I do NOT get the calibration failure even WITHOUT this patch ; if I use gcc 4.8.4 (ELDK 5.6.1rc), I do get calibration failure failure ; if I use gcc 4.7.x (ELDK 5.5.x) and the gcc from ELDK 5.4.x (I don't remember the version), I do get calibration failure failure. I am even starting to suspect compiler bugs here, but I don't want to draw hasty conclusions yet.
btw. where can I get the atlas kit ? it seems out of stock everywhere :(
