I am a bit confused. Sounds like this is affecting the entire U-Boot?
Isn't this just a Cyclone V GEN5 socfpga issue?

It is a very generic setup.
clone from fresh

make clean
make mrproper
make socfpga_cyclone5_defconfig
make prepare

Now please cp .config to .config_default

Ok now
make menuconfig
/WDT turn on and save
make menuconfig
turn all those you have enabled
save again.

then gvimdiff .config .config_default

You will see what I meant.

Enjoy~
Brian
