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).

Hi Stefan, your request to help you with removing more stuff is still in my TODO list - I just do not have time for it.
In short - all this LEB categorization and heaps are also needed for R/O FS and you may remove that large piece of code as well.
