From: Nagabhushana Netagunte <nagabhushana.netagunte@ti.com>

add support for cache management in config file. This is
needed as per new cache management framework. da850 doesnt
support I-CACHE, D-CACHE or L2-CACHE usage which is indicated
by following definitions,

1. CONFIG_SYS_ICACHE_OFF
2. CONFIG_SYS_DCACHE_OFF
3. CONFIG_SYS_L2CACHE_OFF

This commit message makes no sense for me.  You "add support" for
something which essentially is "not supported" as you say.  If you are
trying to fix compile problems, then please say so.

Cheers
