The above changes seem to be moved their positions in the file, and is
not necessary, could you check again?

I think it's better to have 'clear_arsr_reset_status' in generic.c and make
that common for all pxa3xx/pxa93x/pxa95x instead of introducing the same
code all around?

I'd rather we introduce a macro and write this as something like:

Maybe this change could be done in earlier pxa93x separation from pxa3xx patch?

I doubt we need to introduce CONFIG_CPU_PJ4 at this stage, as it's fully
compatible so far with ARMv7. CPU_32v6K will be selected by CPU_V7 except
for OMAP2, and ARM_THUMBEE depends on CPU_V7 and is optional (selectable).
