Rev A2 SoCs have an unorthodox memory re-mapping and this needs to be reflected in the cache operations. This patch adds new outer cache functions for the l2x0 driver to support this SoC revision. It also adds a new compatible value for the cache to enable this functionality. Updates from V1: - remove section 1 altogether and note that in comments - simplify section selection caused by section 1 removal - BUG_ON just in case section 1 shows up Signed-off-by: Christian Daudt <csd@broadcom.com> Reviewed-by: Will Deacon <will.deacon@arm.com> Acked-by: Olof Johansson <olof@lixom.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
