Did you measure the time it takes after power-on before the CPU
executes the first instruction? This is the first system I see that
boots like this, so I'm curious.
Why do you do it this way?

It's not exactly forbidden, but U-Boot does not expect this. And no
other board I've ever seen does it this way.

meant that, pretty soon, there was going to be trouble.
