From 913a39e9aa4d935948d41cd727d53f5878414a77 Mon Sep 17 00:00:00 2001 From: Nagabhushana Netagunte Date: Sat, 3 Sep 2011 22:12:56 -0400 Subject: 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.
