devio binary package in Ubuntu Precise armhf

 devio is a command line program to read correctly from mtd character
 (and other block) devices. devio allows access to specific regions of
 the device and allows output of data from specific locations.
 The primary difference between devio and other command line
 utilities, such as dd and cat, is that it is not stream based - it
 writes directly into the object rather than reading and writing a
 stream of data.
