The entries I touched read (in summary):
config MACH_MVEBU_V7
        bool
        select CACHE_L2X0

config MACH_ARMADA_370
        bool "Marvell Armada 370 boards" if ARCH_MULTI_V7
        select MACH_MVEBU_V7
        help
          [...].

config MACH_ARMADA_375
        bool "Marvell Armada 375 boards" if ARCH_MULTI_V7
        select MACH_MVEBU_V7
        help
          [...].

So the choice I faced was between: 
- using "select PL310_ERRATA_753970 if CACHE_L2X0": that matches all
  current occurrences of "select PL310_ERRATA_*" but adds a superfluous
  dependency on CACHE_L2X0
- using just "select PL310_ERRATA_753970": sufficient, but will break
  if CACHE_L2X0 isn't selected through MACH_MVEBU_V7 anymore.

I chose to just "select PL310_ERRATA_753970" but adding "if CACHE_L2X0"
is fine with me too.

Will do later today.
