Yes please.  If it's needed, just update it to be:

	select PL310_ERRATA_753970 if CACHE_L2X0

for both platforms.  Although there's no harm in using CACHE_PL310 at
the moment, my longer term plan is to eventually kill CACHE_PL310 as
it's entirely redundant for ARM versions of the L2 cache (it's only
used by the old L2x0 code which I've been unable to eliminate entirely.)
