dm6446: disable cache usage due to coherency issues
there are cache coherency issues when using the DAVINCI Ethernet driver, hence caches cant be used for dm6446 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 Signed-off-by: Nagabhushana Netagunte <nagabhushana.netagunte@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
