[U-Boot] [PATCH] dm365: disable cache usage due to coherency issues

From: Nagabhushana Netagunte nagabhushana.netagunte@ti.com
there are cache coherency issues when using the DAVINCI Ethernet driver, hence caches cant be used for d365 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

Denk,
As there are no comments, can you please ACK this patch?
