You mean you need to revert the revert to get U-Boot to run, correct?

As per our IRC discussion, I understand the board just hangs, so I
suspect an exception in SPL, as all exceptions handlers there basically
branch to themselves.

I'd like to know if the board did work between c50afc1d and now, for at
least some commits, or if it never ever worked since c50afc1d.

Also, if running the board under JTAG debug is possible, I suggest
doing so while making sure you'll get control if an exception occurs.
This should tell us which exception occurred and hopefully where and
why.
