[U-Boot] Enabling cache on ARM

Hi Stefano and Albert,

I would like to enable cache on some i.MX boards (ARM9, ARM11 and Cortex-A8).

Are there any boards I could use as a reference on how to properly
implement this?

I thought I should simply do:

#undef CONFIG_SYS_ICACHE_OFF
#undef CONFIG_SYS_DCACHE_OFF

,but still I get a 'WARNING: Caches not enabled' message when I do this.

Thanks,

Fabio Estevam
