Re: [U-Boot] [PATCH] mtest: Disable dcache during test

mtest is supposed to test many types of memory accesses in many different conditions. If dcache is enabled, memory accesses are likely bursts, and some memory accesses are simply skipped. Hence, dcache should be disabled during mtest operation so that what mtest actually tests is not masked by dcache.

if you want dcache disabled, then why don't you run `dcache off` first ? i think it's useful to be able to do both, and forcing it one way is wrong.

thus, NAK from me. -mike
