Introduce the new Kconfig symbol CONFIG_SPL_SYS_L2_PL310 to allow the SPL to build cache-pl310.c. Before this commit, the SPL could enable the PL310 L2 cache [1], but the cache maintenance functions from cache-pl310.c were only useable for non-SPL builds. After enabling the cache one must be able to flush it, too. Thus this commit allows cache-pl310.c to be included in the SPL build. [1] See for example arch/arm/mach-imx/cache.c: v7_outer_cache_enable() Signed-off-by: Philip Oberfichtner <pro@denx.de>
