I can also see this. When I apply all your patches and revert those 3 
commits, SDP boot via uuu and flashing SPI NOR flash with the qspi Image 
works. And then also SPI boot works.
When I don't revert the 3 commit, it does not work. (SDP boot via uuu 
does not work and the Image does not boot when flashed into SPI NOR flash).

I haven't investigated what the problem is or how it can be fixed 
though. So I guess further investigation is needed here.
