[U-Boot] [PATCH] ARM v7: Flush icache when executing a program with go

[Wolfgang Denk]

Dear Henrik Nordström,

This should never be an architecutre specific thing.  Whether we flush
caches or not should be the same on all architectures.

We really need a prototype for this function in a global header file.

Best regards,
