| Yup, and then the final missing piece will be to make sure "kboot"
| can run from RAM when loaded through JTAG. Thus the devirgination
| sequence becomes:
We have to find a new verb / figleaf for this that is more neutral --
| - insert SD card with Linux kernel and rootfs
| - load "kboot" over JTAG
| - boot from SD card
| - system on SD card copies "kboot" and anything else we want there
| to NAND
| - after that, you can update the NAND just from Linux, much like
| we do in FINAL
It's a shame if we have to support NAND in Linux at all. Better that
NAND is the dirty secret we never acknowledge, if possible.

| doesn't already come with a USB firmware loader, DFU would be quite
| handy for that.
Fair enough, can conceivably be useful there. But no longer for
