If you were to utilize the partitioning method in the 'pnc2000.c'
as we discussed earlier and place a "superblock" of sorts at the
beginning of the JFFS image that contained a linked list of where
the nodes are located either logically offset within the MTD
partition or physically addressed in the flash. This "superblock"
would be a pre-allocated size created when the JFFS image is built
on the host platform. That's a really quick idea with not a whole
lot of technical accuracy.
