Eric,

At first, a new macro (ARCH_PXA_V7) is defined in
arch/arm/mach-pxa/Kconfig in this patch.
I prefer to move this macro to arch/arm/Kconfig.

Secondly, pxa95x is both used in saarb and tavorevb3.

Thirdly, PXA_V7_MACH_AUTO is unnecessary. We just need to select those
machines in defconfig or define a new DT machine type to select all
machines.

Thanks
Haojian
