Hi Rohit,

I have a couple of patches (attached) that add yaffs2 support for 
buildroot, that I have never got round to pushing upstream. They are 
based on buildroot_2013.05.

Regards
Will

I've taken your two patches, made a little bit of clean up, and I
applied them.

Thanks!

Well, pull the latest Buildroot, and in the "Filesystem images" menu,
you'll have a yaffs2 option. Simply enable it, and Buildroot will
generate a yaffs2 image of the root filesystem.
