Hi,

As a part of our NAND Flash Framework project we would like to add a new 
geom class which allows to divide NAND Flash chip into partitions.
Nand is divided into partitions based on data in dts file.

The purpose of having this geom class is to separate part of nand chip 
device which might contain some crucial data like u-boot image, 
parameters, etc. into separate devices and use the rest of nand to store 
user data.

Patch can be found at:
http://people.freebsd.org/~gber/patches/slicer.patch
it contains geom flashmap code along with changes in FDT area and 
changes in DTS file for SheevaPlug.

Please let me know if you have any comments or objections.

thanks,
grzesiek
