May look as if it's the right thing to do, but there's symbols lower down
(PL310_ERRATA_*) which are selected which depend on this symbol being
enabled.

What this means is that it's now possible for OMAP to be configured with
CACHE_L2X0 disabled _and_ for the PL310_ERRATA_* options to be forced on,
which results in:

warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_588369 which has unmet direct dependencies (CACHE_L2X0)
warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_727915 which has unmet direct dependencies (CACHE_L2X0)

So, let's clean up this sillyness by doing the job properly - ensuring
that /all/ PL310_ERRATA_* symbols are selected conditionally on
CACHE_L2X0 (whether or not CACHE_L2X0 is selected), so when people remove
that select statement, it doesn't cause these kinds of side effects.

The patch below will be in linux-next tomorrow.

From: Russell King <rmk+kernel@arm.linux.org.uk>
Subject: [PATCH] ARM: l2c: fix dependencies on PL310 errata symbols

A number of configurations spit out warnings similar to:

warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_588369 which has unmet direct dependencies (CACHE_L2X0)
warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_727915 which has unmet direct dependencies (CACHE_L2X0)

Clean up the dependencies here:
* PL310 symbols should only be selected when CACHE_L2X0 is enabled.
* Since the cache-l2x0 code detects PL310 presence at runtime, and we will
  eventually get rid of CACHE_PL310, surround these errata options with an
  if CACHE_L2X0 conditional rather than repeating the dependency against
  each.
