bdc5f06789 UBI: Fix problem in UBI/Linux "compatibility layer"
"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.

d8bc55a6fb Move uninitialized_var() macro from ubi_uboot.h to compiler.h
This is needed so that we could use this macro for non-UBI code.

9eefe2a2b3 UBIFS: Implement read-only UBIFS support in U-Boot
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).

2ee951ba2a UBI: Enable re-initializing of the "ubi part" command
With this patch now, the user can call "ubi part" multiple times to
re-connect the UBI device to another MTD partition.

7e6ee7ad27 UBI: Add basic UBI support to U-Boot (Part 6/8)
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.
