May I ask _why_ you would want to do this in the first place?

It does not seem to make sense to me.

Please also note that "mtest" is basicly useless.  Totally useless,
to be honest.  It performs plain read / write cycles, and unless you
have very basic memory issues this will always work - if you have
such, these get detected when running get_ram_size().

"mtest" was once added as an explicit requirement of a customer to
meet some formal specification requests. It is a ZERO practical use.

If you want to do memory testing, then use the memory test functions
of the POST framework.  OK, these will not exercise any burst mode
accesses either, but they are at least a bit more useful.

Best regards,

Wolfgang Denk
