there are cache coherency issues when using the DAVINCI Ethernet driver, hence caches cant be used for da850 u-boot. 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
