Booting from JFFS2

This is for a sh4-based board. There are two boot loaders
available: lilo and ipl+sh. From your answer, I assume
that none of the boot loader out there understands JFFS2
My next option is to partition the flash into three: (1)
bootloader, (2) ext2 for kernel/initrd, (3) JFFS2 for the
rest of the filesystem's mount points.

The answer to that question is entirely dependent on the bootloader you
use. But at the moment, I think there are no bootloaders which support this.
There are patches available for Compaq bootldr used on the iPAQ, which make
it capable of loading a kernel from a JFFSv1 filesystem. But nobody's yet
done JFFS2, AFAIK.
We're intending to add this support to RedBoot some time in the near
