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.
