[U-Boot-Users] Command "dcache on" for MPC850 isn't valid

Hi All,

I got a problem recently and have to send this mail for resolution. The 
configuration I'm using:

CPU:     MPC8xx
U-boot: 1.1.4
Linux   : 2.6.15
ELDK  : 4.0

As everyone knew, uboot for MPC850 didn't turn on data cache, but 
instruction cache is on. In order to test data cache, I added 
CFG_CMD_CACHE  for CONFIG_COMMANDS. However, the CPU is spinning once I 
issue command "dcache on".

Any ideas on this?

Thanks,
Gavin
