It is possible. Just include your uImage into your JFFS2 image and load it 
from u-boot using fsload. Make sure you include the proper commands into u-
boot. But beforehand you have to setup mtdparts so u-boot knows where to 
search for JFFS2 filesystem. The current partition is changed using 'chpart'.
