* UBIFS: fix recovery bugAdrian Hunter2009-04-28-47/+23
| | | | | | | | | | | | UBIFS did not recovery in a situation in which it could have. The relevant function assumed there could not be more nodes in an eraseblock after a corrupted node, but in fact the last (NAND) page written might contain anything. The correct approach is to check for empty space (0xFF bytes) from then on. Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com> Signed-off-by: Stefan Roese <sr@denx.de>
* UBIFS: Implement read-only UBIFS support in U-BootStefan Roese2009-03-20-0/+1249
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).
