Currently mx6ul evk fails to boot with some SD cards such as SanDisk microSD HC - 8GB:
U-Boot SPL 2016.05-rc1-28384-g108f841 (Apr 19 2016 - 11:19:11) Trying to boot from MMC1 spl: mmc block read error SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ###
As a proper fix for SPL is not available, change to booting via non-SPL mode, so that we can have always have a reliable boot.
