This DT property allows marking flash partition that Linux should use as
a root device. It's useful for devices that don't use U-Boot and cmdline
parser for partitioning. It may be used with "fixed-partitions" or some
dynamic partitioning based on flash content.

This gets rid of "nvmem-cells" limitation. Dynamic partitions can be
defined for any (sub)partitions layout.

Backport upstream solution that permits to declare nvmem cells with
dynamic partition defined by special parser.
This provide an OF node for NVMEM and connect it to the defined dynamic
partition.

Check if gendisk is already up instead of trying to figure out parent
mtd device (which didn't work well).

Move 480-mtd-set-rootfs-to-be-root-dev.patch to hack-5.10 and fix assumption
about the block device index.

Allow using the FIT block-device partition partition parser to work on
top of mtdblock devices.
This is more tricky than it sounds as it requires to reorganize the
procedure of registering mtdblock devices in order to avoid locking
troubles caused by the block partition parsers then trying to open
the mtdblock device for reading while locks are still being held.
Fix that by moving the adding of the disks after the entire device
has been probed when locks no longer need to be held.
Also address issue with mtdsuper surfaced when using sub-partitions
which prevented mounting JFFS2 using the /dev/mtdblock* device.
