Instead of enumerating all SoC families that need that bit set, let's just express this more clearly: The SMP bits needs to be set on SMP capable ARMv7 CPUs. It's much easier in Kconfig to express it the other way round, so we use ! CPU_IS_UP and ! ARM64.

booldefault nBetter to place this in sunxi, since no other code using this expect sunxi and the name CORTEX may also refer arm64 use something 32 related.
Sigh, can you please check back with Maxime on what's the right thing here? http://lists.denx.de/pipermail/u-boot/2017-January/279417.html
If it's about the name, shall we use ARM_CORTEX_V7_CPU_IS_UP?
I was briefly tempted to unify all ACTLR.SMP bit sets from all over the ARM code, but this looks like a can of worms to me, so I'd rather keep this one closed.
Cheers, Andre.
