As per new cache management framework,if the caches are not used in u-boot, it needs to be explicitly indicated through macros in config file. CACHE disable is indicated by the following macro definitions in config file, 1. CONFIG_SYS_ICACHE_OFF 2. CONFIG_SYS_DCACHE_OFF 3. CONFIG_SYS_L2CACHE_OFF Signed-off-by: Nagabhushana Netagunte Acked-by: Ben Gardiner --- include/configs/da850evm.h | 3 +++ 1 files changed, 3 insertions(+), 0 deletions(-) diff --git a/include/configs/da850evm.h b/include/configs/da850evm.h index bbb5a9b..fdcc6e3 100644 --- a/include/configs/da850evm.h +++ b/include/configs/da850evm.h @@ -42,6 +42,9 @@ #define CONFIG_SYS_HZ 1000 #define CONFIG_SKIP_LOWLEVEL_INIT #define CONFIG_SYS_TEXT_BASE 0xc1080000 +#define CONFIG_SYS_ICACHE_OFF +#define CONFIG_SYS_DCACHE_OFF +#define CONFIG_SYS_L2CACHE_OFF /* * Memory Info
