*	UBIFS: add R/O compatibility	Artem Bityutskiy	2009-04-04	1	-6/+28
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Now UBIFS is supported by u-boot. If we ever decide to change the media format, then people will have to upgrade their u-boots to mount new format images. However, very often it is possible to preserve R/O forward-compatibility, even though the write forward-compatibility is not preserved. This patch introduces a new super-block field which stores the R/O compatibility version.

*	UBIFS: Implement read-only UBIFS support in U-Boot	Stefan Roese	2009-03-20	1	-0/+324
	The U-Boot UBIFS implementation is largely a direct copy from the current Linux version (2.6.29-rc6). As already done in the UBI version we have an "abstraction layer" to redefine or remove some OS calls (e.g. mutex_lock() ...). This makes it possible to use the original Linux code with very little changes. And by this we can better update to later Linux versions. I removed some of the Linux features that are not used in the U-Boot version (e.g. garbage-collection, write support).
