It can just depend on CACHE_PL310 as this depends on CACHE_L2X0.

Same here.

CACHE_L2X0 has a long dependency list. You could add ARCH_OMAP4 in
there or just change the other platforms to select a HAVE_CACHE_L2X0.
Ideally we would like this option to be selectable in config just in
case you want to debug some issues.

This part together with the Kconfig changes for OMAP4 could be a
separate patch, OMAP-specific.
The rest seems fine.
