Oh! Well, to start with apparantly u8500_defconfig doesn't have
APPENDED_DTB enabled, which explains some of the confusion here.

With that fixed (and the appropriate options to get the bootargs from
the atags), I get as far as console probing where output stops, if I
have DEBUG_LL on. With it disabled I get all the way up.

Not sure what was going on earlier here. Maybe just as in your case it
was a matter of cleaning out and starting fresh.

multi_v7_defconfig still doesn't boot though, but the failure seems to
be lower level than any of the others, no output with DEBUG_LL on.
