In late October 2008, according to the git logs, the methodology for
selecting a processor on several boards, at least the Versatile PB board was
changed so that it automatically selects CPU_ARM926T as a hidden symbol.
The reason I have a question, is since QEMU currently can emulate a
Versatile PB board with other processors than just the ARM926T (Such as the
ARM1136 (ARMv6) and Cortex-A8 (ARMv7), is there a good way to allow that in
the mainstream kernel? Previously the patch was to just add extra potential
dependencies on CPU_V6 and CPU_V7, so that by selecting MACH_VERSATILE_PB,
you could select ARMv6/v7 support.

Currently I'm just deleting the select statement, and having all the CPUs
appear, as no longer hidden symbols. My question is, what is the best way to
allow for other processors for this board in Kconfig, so it could be
submitted to the mainstream kernel?
