The config option for L2x0/PL310 doesn't get selected for this platform.
Rather than bloat the list in arch/arm/mm/Kconfig each time we add a
coretile (and get a merge conflict with anyone else adding a platform
with an L2CC) I've posted a patch to attempt to factorise that:
ARM: pl2x0/pl310: Refactor Kconfig to be more maintainable
If this looks OK and nobody objects, I suggest to build on top of that.
Note that select PL310_ERRATA_753970 if CACHE_PL310 also needs to be
propagated to ARCH_VEXPRESS_CA9X4. Maybe we should have a common symbol
which selects/depends on the common stuff instead of duplicating it for
every coretile -- they will tend to get out of sync.
Cheers
