* Conditionally perform common relocation fixupsPeter Tyser2009-10-03-0/+4
| | | | | | | | | | | Add #ifdefs where necessary to not perform relocation fixups. This allows boards/architectures which support relocation to trim a decent chunk of code. Note that this patch doesn't add #ifdefs to architecture-specific code which does not support relocation. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* ubifs: Correct dereferencing of files-after-symlinksSimon Kagstrom2009-09-28-1/+1
| | | | | | | | | | | | | | | | | Files in directories which are symlinked to were not dereferenced correctly in last commit. E.g., with a symlink /boot/lnk -> /boot/real_dir loading /boot/lnk/uImage will fail. This patch fixes that by simply seeing to it that the target base directory has a slash after it.

* ubifs: Add support for looking up directory and relative symlinksSimon Kagstrom2009-09-23-25/+43
| | | | | | | | | This patch adds support for resolving symlinks to directories as well as relative symlinks. Symlinks are now always resolved during file lookup, so the load stage no longer needs to special-case them.

* Move __set/clear_bit from ubifs.h to bitops.hSimon Kagstrom2009-09-15-32/+0
| | | | | | | | | __set_bit and __clear_bit are defined in ubifs.h as well as in asm/include/bitops.h for some architectures. This patch moves the generic implementation to include/linux/bitops.h and uses that unless it's defined by the architecture. Signed-off-by: Simon Kagstrom <simon.kagstrom@netinsight.net>
* ubifs: fix small error path mismatchDaniel Mack2009-06-09-4/+2
| | | | | | In do_readpage(), don't free 'dn' if its allocation failed. Signed-off-by: Daniel Mack <daniel@caiaq.de>
* ubifs: BUG: Blocks commpressed with zlibRicardo Ribalda Delgado2009-04-30-3/+5
| | | | | | | | Blocks compressed with zlib dont have the full gzip header. Without this patch, block compressed with zlib cannot be readed! Signed-off-by: Ricardo Ribalda Delgado <ricardo.ribalda@uam.es>
* ubifs: BUG realpath string must be ended with NULLRicardo Ribalda Delgado2009-04-28-0/+1
| | | | | | | | If the memory used to copy the link_make is "dirty" the string wont be ended with NULL, throwing out multiple memory bugs. Signed-off-by: Ricardo Ribalda Delgado <ricardo.ribalda@uam.es> Acked-by: Stefan Roese <sr@denx.de>
* UBIFS: Remove tnc_commit.c which is not used in the read-only versionStefan Roese2009-04-28-1102/+0
| | | | | | | | I missed removing this file while implementing the UBIFS support. It's not referenced at all, so let's remove it. Thanks to Artem Bityutskiy for spotting. Signed-off-by: Stefan Roese <sr@denx.de>
* 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: add R/O compatibilityArtem Bityutskiy2009-04-04-11/+71
| | | | | | | | | | | | | | | 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: 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).
