Hi all,

I have a custom board based on Altera Cyclone V SoC, when I tried to boot
from QSPI, it stuck in a boot loop, I try to enable some debug message, and
here it is:

U-Boot SPL 2016.09.01 (Oct 03 2016 - 18:14:42)

u-boot from Altera working fine, but I plan to use the mainline u-boot. Any
idea why it does not work?
