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 Signed-off-by: Sandeep Paulraj --- diff --git a/include/configs/davinci_dvevm.h b/include/configs/davinci_dvevm.h index 45214fa42a..086a2d7d40 100644 --- a/include/configs/davinci_dvevm.h +++ b/include/configs/davinci_dvevm.h @@ -60,6 +60,9 @@ #define CONFIG_SYS_HZ_CLOCK 27000000 /* Timer Input clock freq */ #define CONFIG_SYS_HZ 1000 #define CONFIG_SOC_DM644X +#define CONFIG_SYS_ICACHE_OFF +#define CONFIG_SYS_DCACHE_OFF +#define CONFIG_SYS_L2CACHE_OFF /*====================================================*/ /* EEPROM definitions for Atmel 24C256BN SEEPROM chip */ /* on Sonata/DV_EVM board.
