From 46203baf665c6bab72bd5945a37d9a7e0a77699a Mon Sep 17 00:00:00 2001 From: Daniel Schwierzeck Date: Fri, 7 Sep 2018 19:02:06 +0200 Subject: [PATCH] MIPS: cache: remove config option CONFIG_SYS_MIPS_CACHE_MODE Caches should be configured to mode CONF_CM_CACHABLE_NONCOHERENT (or CONF_CM_CACHABLE_COW when a CM is available). There is no need to make this configurable.
