It compiles and it works!

On sockit:

U-Boot SPL 2016.03 (Apr 05 2016 - 17:57:23)
drivers/ddr/altera/sequencer.c: Preparing to start memory calibration
drivers/ddr/altera/sequencer.c: CALIBRATION PASSED
drivers/ddr/altera/sequencer.c: Calibration complete
Trying to boot from MMC1

First time that an SPL built from a recent version has run successfully
on that board.

Will try it out on de0 tomorrow morning...

Thanks!
