[PATCH 0/6] Fix 740t support and remove more unused ARMv3 code

Hello,
When looking at the remaining ARMv3 code that we still have kicking
around, I noticed that the only user of the cache-flushing routines is
the 740t, an ARMv4 chip. Having read the datasheet, we can actually use
our ARMv4 cache-flushing code and remove cache-v3.S.
After making that change, I thought I'd better do some testing, which is
where the fun began...
Even after getting hold of a 740t Integrator/AP core-tile, I ran into
many problems with the CPU support, which I don't believe has *ever*
worked. Anyway, having fixed those, the board runs like a charm.
Next stop is the 940t, which looks to be broken in similar ways.
