[PATCH 01/13] ARM: Exynos: initialize l2x0 cache controller only for cortex-a9 based SoCs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Only cortex-a9 based Exynos SoCs have l2x0 cache controller. Hence instead of
checking for every SoC with soc_is_xxx, just check for cpu part number and
initialize the cache controller for cortex-a9 based SoCs.
