[U-Boot] [bug report]cmd: cache: output information
Hi guys,
I think the output of command 'dcache' is improper. It always print 'writethrough' regardless of the real policy, such as write back.
=> dcache Data (writethrough) Cache is ON
Not only ARM but also other socs support cache, hence we can't differentiate policy by macro (i.e CONFIG_SYS_ARM_CACHE_WRITETHROUGH). Can you think of anything better?

I'm sure it could be improved. Perhaps it could also be done in a generic way so it works on all archs. Do you want to send a patch?

Hi Simon,
I'm not very familiar with other archs except, hence I'm not able to implement it.:-(

Well a patch for ARM would be useful. I'm sure other people could add to it later.
