[U-Boot] I want to a board(tiny4412) for exyno4412, but I can't get any output

The patch in below, but it doesn't work.
I can get any output from build of below, I don't build SPL(BL2), I just
use the one from manufacturer. I don't know whether it caused by
security boot.
The source code is modified from trats2.
As this board doesn't have any PMIC, it just use some static power chip
to convert voltage level, I remove all the code about PMIC.
