[Yaffs] yaffs2 problem

Hi:
    I want to use yaffs2 in my company's project, and I am evaluating it, we will buy it if it can work well in my project.
so I have download the source code from your  website http://www.aleph1.co.uk/gitweb?p=yaffs2.git;a=summary ;
problems are these:

1: After  unpacked the tar,i go into the path yaffs2-7e5cf0f\yaffs2-7e5cf0f\direct,and  i can not find the yaffscfg.c.  why?
i think this is important for me to use direct interface.

2:My hardWare environment is ARM9 ，MICRON NANDFLASH MT29F8G08ABABAWP（1 Page = 4K + 224bytes）,
   Soft environment  is ucos3 os.   yaffs2 can be used in my situation?

thanks!
