I work with Fabio Ubaldi. The problem is this: the new linux kernel
image is send to system from a remote site and the system has to update
the image automatically. Our ideas was this: after the system had
mounted the jffs2 linux kernel partition, it copy the new image in
/mnt/kernel (jffs2 linux kernel partition) and after that the system is
rebooted. To perform this U-Boot must be able to boot a linux kernel
image from a jffs2 partition. I hope that the problem is now more clear.
