The UBI layer will disable much of its error reporting when it is
compiled into the linux kernel to avoid stopping boot. We want this
error reporting in U-Boot since we don't initialize the UBI layer until
it is used and want the error reporting.
We force this by telling the UBI layer we are building as a module.

"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.

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).

With this patch now, the user can call "ubi part" multiple times to
re-connect the UBI device to another MTD partition.

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.
