From ace3be4f15875d74344336b9754c14274f940969 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Fri, 27 May 2016 14:28:04 +0100 Subject: MIPS: Move cache sizes to Kconfig Move details of the L1 cache line sizes & total sizes into Kconfig, defaulting to 0. A new CONFIG_SYS_CACHE_SIZE_AUTO Kconfig entry is introduced to allow platforms to select auto-detection of cache sizes, and it defaults to being enabled if none of the cache sizes are set by the configuration (ie. sizes are all the default 0), and code is adjusted to #ifdef on that rather than on the definition of the sizes (which will always be defined even if 0).
