  Log:
  SVN rev 220559 on 2011-04-12 08:10:25Z by adrian
  
  Introduce geom_map, a GEOM provider designed for use by
  embedded flash stores.
  
  Some devices - notably those with uboot - don't have an
  explicit partition table (eg like Redboot's FIS.)
  geom_map thus provides an easy way to export the hard-coded
  flash layout as geom providers for use by filesystems and
  other tools.
  
  It also includes a "search" function which allows for
  dynamic creation of partition layouts where the device only
  has a single hard-coded partition. For example, if
  there is a "kernel+rootfs" partition, a single image can
  be created which appends the rootfs after the kernel with
  an appropriate search string. geom_map can be told to
  search for said search string and create a partition
  beginning after it.
