[Yaffs] yaffsdev.c missing

Hi,

I am currently pursuing my academic project on yaffs2, garbage collection
heuristics to be more precise. I need to perform extensive testing on
yaffs_guts.c. With reference to http://www.yaffs.net/yaffs-development-notes,
yaffs1 could be tested using yaffsdev.c, but I did not find any support for
yaffs2. What is the current state of yaffsdev project? Where can I find the
lastest file and any pointers as to how I can build yaffs as an application
as stated in the reference.

Thank You
Dhruv
