From: Rob Herring <redacted> Add empty version of l2x0_of_init for when CONFIG_CACHE_L2X0 is not selected. Signed-off-by: Rob Herring <redacted>
Acked-by: Barry Song <redacted> it seems most people use " #ifdef CONFIG_CACHE_L2X0 ... l2x0 related codes ... #endif " or " obj-$(CONFIG_CACHE_L2X0) += xxx-l2x0.o " to avoid l2x0 related codes compiled and linked into kernel. but this patch provides another option. it is not bad too.
