* UBIFS: Missing offset relocation for compressor 'none'Michael Lawnick2009-03-20-1/+4
| | | | | | | | | | | On systems where U-Boot is linked to another address than it really lays (e.g. backup image), calls via function pointers must be fixed with a '+= gd->reloc_off'. This was not done for none_compr in ubifs_compressors_init() what leads to system crash on ubifsmount command. Signed-off-by: Michael Lawnick <ml.lawnick@gmx.de> Acked-by: Stefan Roese <sr@denx.de>
* UBIFS: Implement read-only UBIFS support in U-BootStefan Roese2009-03-20-0/+16971
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).
