Override the default go/boote handlers as we want to disable both data and instruction cache before executing external programs (since Blackfin cache handling requires a software handler in U-Boot which may be overwritten).
Umnmm... no. "go" is supposed to be return to U-Boot, i. e. it must not overwrite (or otherwise meddle with) any U-Boot code.
I think you should not change cache status for "go".
reality is that people often times use go to execute their binary blobs. i also see it this way: go means to jump to some address and most likely never return. -mike
