From 2e8d68e241b35d383a057b014287a756624a32bc Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Fri, 24 Apr 2020 20:20:16 +0200 Subject: arm: caches: add DCACHE_DEFAULT_OPTION Add the new flags DCACHE_DEFAULT_OPTION to define the default option to use according the compilation flags CONFIG_SYS_ARM_CACHE_*. This new compilation flag allows to simplify dram_bank_mmu_setup() and can be used as third parameter (option=dcache option to select) of mmu_set_region_dcache_behaviour function.
