Using the attached Makefile (for a Montavista 2.4.18 xscale kernel) from the
original yaffs Makefile.
I don't have the new MTD working with this kernel (I don't have a choice to
upgrade to a new kernel either). So, I patched the yaffs_fs.c file, and
only used the yaffs_mtdif.c (not sure if this will break anything yet).
It compiles now with warnings. I will look into the warnings first then
give it a try on my target machine.
I've included the small patch, and the Makefile (you will have to modify it
to work in your build system).

Subject: [Yaffs] YAFFS2 on Linux checked in
The YAFFS2 for Linux stuff to work with mtd is now checked in.
I have tested this with a mtd "device" that is actually ram dressed up to
look like nand.
Let the sports begin!
