No problem, I didn't label it as RFC since what it does is actually fix a
regression.

At one point U-boot was working on the Integrator and now
it doesn't, it seems commit 880eff5cfb9df6f0855f4e48affd349ca64692e9
"ARM: cp15: setup mmu and enable dcache" is causing it.

Heiko, Alessandro, do you have any hints on how to go about flushing
and disabling the D-cache in bootm for ARM920T? It doesn't seem to
work on this ARM CPU chip in its current form...

Yours,
