[Joel Fernandes]

Disabling the I, D and L2 cache makes us able to detect the ethernet device.

In board config,
#define CONFIG_SYS_ICACHE_OFF
#define CONFIG_SYS_DCACHE_OFF
#define CONFIG_SYS_L2CACHE_OFF

Just CC'ing Aneesh as well as I believe he authored these patches:

Commits:
e05f007 arm: minor fixes for cache and mmu handling
c2dd0d4 armv7: integrate cache maintenance support
e47f2db armv7: rename cache related CONFIG flags
2c451f7 armv7: cache maintenance operations for armv7

Thanks,
Joel
