[RFC] UBIFS unpacker v0

[Richard Weinberger]

Hi!

This is the first public release of the UBIFS unpack tool.
Using this tool you can unpack an UBIFS to a local directory,
it can operate directly on UBI volumes (i.e. /dev/ubiX_Y)
or nanddumps (without OOB!). If you dump from a nandump,
you have to specify the UBI volume ID you want to dump from.
So far it is rather strict and refuses to unpack if the filesystem
is corrupted. We plan to implement also a "fuzzy unpack" mode.

The patches apply on Yang's mtd-utils restructure work.

Thanks,
//richard
