[U-Boot-Users] dcache on ads5121e

Using HEAD 6bc113886d7d316df1a4e459bec8baf027518551

When I set CONFIG_CMD_CACHE and then use the command "dcache on" to turn
on cache I lose the serial port. u-boot is now just spinning on the
serial receive but it never gets any input.

Anybody run with caches on ??

The functions (in start.S ) was implemented. Kind of pointless if cache
can only be used with a mmu.
