OK. It seems the interrupt code is more broken than I thought - the
udelay implementation relies on a variable that is set *before*
relocation - in BSS.
Rather than trying to fix this, I will remove the broken parts.
I'll do some more cleanup next week, test all boards I have here, and
post patches for review.
