Yes. Just for the records: mtd/0 is the entire flash, the partitions
are counted starting with mtd/1 etc. With ppcboot fsinfo,fsload you
can access your jffs file systems.

Another option is to put the kernel image into a raw mtd partition
(eg. cat pImage >/dev/mtd/1). You can then load it from ppcboot with
the regular bootm command. This is faster than using jffs, but of
course the kernel image will not take advantage of the wear levelling.
