* UBI: Fix problem in UBI/Linux "compatibility layer"Stefan Roese2010-05-191-1/+1
| | | | | | | | "down_write_trylock" needs to return 1 instead of 0 for success. Otherwise copying a block with a read error (e.g. bit-flip on read) won't work correctly. Signed-off-by: Stefan Roese <sr@denx.de>
* Move uninitialized_var() macro from ubi_uboot.h to compiler.hAnton Vorontsov2009-09-041-3/+1
| | | | | | This is needed so that we could use this macro for non-UBI code. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com>
* UBIFS: Implement read-only UBIFS support in U-BootStefan Roese2009-03-201-1/+8
| | | | | | | | | | | | | | | 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).

* UBI: Enable re-initializing of the "ubi part" commandStefan Roese2008-12-091-0/+1
| | | | | | | With this patch now, the user can call "ubi part" multiple times to re-connect the UBI device to another MTD partition. Signed-off-by: Stefan Roese <sr@denx.de>
* UBI: Add basic UBI support to U-Boot (Part 6/8)Kyungmin Park2008-11-191-0/+217
This patch adds basic UBI (Unsorted Block Image) support to U-Boot. It's based on the Linux UBI version and basically has a "OS" translation wrapper that defines most Linux specific calls (spin_lock() etc.) into no-ops. Some source code parts have been uncommented by "#ifdef UBI_LINUX". This makes it easier to compare this version with the Linux version and simplifies future UBI ports/bug-fixes from the Linux version.
