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

Hi Grzegorz,
Long time ago I was add to my todo list item to add FDT support to
geom_map module. Now you have good replacement.
(/me cut off one item from todo)
Just one question:
it is possible to not assume that parent media is NAND?
+ if (g_io_getattr("NAND::device", cp,&size,&dev))
+ break;

Hi Alexandr,
It seems to be doable. It requires additional testing and additional
review. We would like to apply this patch now. And then if necessary
this mechanism might be changed to allow other types of devices.
thanks,
grzesiek
