uImage is the firmware including both kernel and application.

In our solution, application and kernel are wrapped into on firmware. I'm
not sure it's accurate enought to call it uImage.
My question is:
Supposing pure data(kernel and application) is 8M, and NAND flash is 32M,
then how many bytes|blocks JFFS2 file system will occupy by itself, such as
wearing level, gc algorithm, JFFS2 INODE header... ?
