As a result of a design discussion, we have resized some partitions of the NAND of the CC6UL as described in https://confluence.digi.com/display/CCUL/New+partition+layout+for+CC6UL.

I have merged the change yesterday to the source code. Starting from last night on our build server (and in next U-Boot release), U-Boot will default to the new partition table. Remember that the NAND partition table is nothing else than a string saved in U-Boot environment variable 'mtdparts'. To make use of the new layout you need a new U-Boot and restore the default environment (once you have booted the new U-Boot). Then, it is recommended that you erase the partitions prior to update again the system in the nand:

- Boot target with new U-Boot ⇒ env default -a ⇒ saveenv ⇒ mtdparts (this only lists the new partition layout) ⇒ nand erase.part linux ⇒ nand erase.part recovery ⇒ nand erase.part rootfs

and then update the partitions with a new system. Erasing the partitions is recommended to start with clean UBI metadata.
