At this stage there is no prebuilt unyaffs. Interestingly, someone else asked 
for the same thing off-list a few days back.

Here's a relatively easy way to do this, but needs some coding.

Starting with yaffs direct, modify yaffs_fileem2k.c to match the dump file 
layout.

Write an application using yaffs direct that recursively iterates through the 
mounted fs and writes the directories/files to the host file system. The 
basic form of such an app is in mkyaffs2image (substituting file access 
functions with yaffs_xxx equivalents).
