-This patch adds support for 'dynamic partitions'. This basically
-works as follows:
-* The nand code generates a bad-block-table at the first scan of the chip
-* The dynamic partition code calculates the raw partition sizes based on
- the bad block table. E.g. if you have a partition of size 0x30000, and there are
- two bad blocks (0x4000 each) in it, the raw size will increase to 0x38000, and the
- following partitions get shifted towards the end of flash.
-
-Please note that currently the desired partition sizes are stored at compile-time
-in an array in drivers/nand/nand_bbt.c, so this definitely needs to change before
-submitting/merging upstream.
-
-In order to calculate the partiton map (and set mtdparts accordingly), you can use
-the 'dynpart' command at the prompt. Use 'saveenv' to make the setting permanent.
