Hi,
in attachment GEOM module to support MTD partitioning.
All systems in which I have seen support MTD partitions do it via values in source code.
For more convenient change the partitions, I use hints.
Example hints file also in attachment.
In this example one of partitions (0x00040000-0x003e0000) split by keyword '--PaCkImGs--' into two partitions ("kernel" and
"roots")
Others think things will be clear from the file itself.
