Anyone porting YAFFS2?

[Bruce M. Simpson]

Has anyone out there considered porting YAFFS2 to FreeBSD? Looking at 
the design notes it sounds fairly portable, more so than JFFS2:

This could be a good test case for flash support as it seems that a 
NEWBUS interface could be implemented for flash controllers, which 
YAFFS2 could then use.

I'm not sure how GEOM would fit into this picture. The file system glue 
strikes me as a minimal amount of work compared to the rest involved in 
supporting this.

Whilst the code is available under GPL, the author(s) state that they 
are 'open to arrangements'; I'm not sure what this implies, the 
licensing information on their site suggests this is about negotiating 
commercial licenses with them. It would seem acceptable to me that such 
code could potentially be imported under src/sys/contrib, however, this 
leaves the question of what we do about firmware images which 
incorporate such a YAFFS2 build.
