[U-Boot] Updating YAFFS2 RootFS

Hi,

I'm looking to update the linux yaffs2 rootfs from U-Boot (2009-06). The whole update will be:

* Take the rootfs.tgz from the yaffs2 "image" partition (ok, with yrdm / ywrm) for update or restore purposes.

* Unpack it (maybe gunzip)

* Update the Linux YAFFS2 RootFS (how ?)

After a quick search (mail list, code) seems that:

* No native support for this operation in u-boot.

* Some "user" patch files exists (out of date ?)

So, my questions:

* Is the situation really like that ?

* Which is the actual patch file ?

* What about the future for YAFFS2 in U-Boot ? Is there any update planned ?

Regards

David
