ARM: mm: fix numerous hideous errors in proc-arm740.S
The setup code in proc-arm740.S is completely broken and, as far as I
can tell, always has been. I was >this< close to ripping it out, when a
740t core-tile materialised in the office, so I've had a crack at fixing
things up:
- Fix the ram/flash area calculations so that we actually set
the condition flags before testing them...
- Fix the proc_info structure so that __cpu_io_mmu_flags are
defined as 0, placing the __cpu_flush pointer at the correct
offset
- Re-number the registers used during __arm740_setup so that
we don't clobber the machine ID et al
- Advertise Thumb support via the hwcaps, since 740T is the only
740 implementation.
