I understand a bit about setting up JFFS2 and have used drivers/mtd/maps for this purpose. I also understand that in setting up UBIFS, I will enable UBIFS in the linux kernel.
But, on the flash, I am a little perplexed as I have not done this before.
Can someone give me a few hints and clues about setting up the flash in the manner Eric describes, please?

It has a description of how to set up a ubifs image (under "Generate UBIFS IMage") and how to write a kernel and ubifs image to NAND flash (in step 5 of "Get the DockStar Going").
This all presumes that you have a partitioning scheme set up on your flash. If you're starting from scratch or completely overwriting someone else's firmware, you can set up whatever you want (you'll want to learn about the mtdparts kernel boot parameter). Otherwise, you can use the existing system to find out what it is (try "cat /proc/mtd" if it's running an embedded Linux).

Oops. Maybe I need to back up a tiny bit here.
I have a NOR flash, not a NAND flash.
I have been trying to compile UBIFS into u-boot for the last little while and keep stumbling over NAND unresolveds at link time. So, I have to ask the question: "Is it reasonable to expect UBIFS to work in NOR flash on a MPC8323ERDB with u-boot-2011.03 and if so, what might be the pitfalls?"
