I tend to agree with Hans - this should normally be implemented in a
script, or, if reallyneeed (but I can't ssee why this would be
necessary) in board specific code.

If added as a generic feature, then there should be options to select
which range of the device to use for testing.  It may be interesting
to test specific areas (like at the assumed end of the device), or at
least to be able to respect existing partitions etc.

But still - I can't see why this would be needed - plain reading and
writing to the device or even to a file in a file system should
perform the same task.

Best regards,

Wolfgang Denk
