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:
- insert SD card with Linux kernel and rootfs
- load "kboot" over JTAG
- boot from SD card
Well, this sounds good. But it seems that we need to keep test points
for SDIO.
This is reserved for *production* usage entirely if we want the
devirgination looks like this.
As I know, PCB space is limited now. We need to let HW/PE people know
this in advance.

- 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
BTW, DFU may still have a future: if we get a USB-capable MPU that
doesn't already come with a USB firmware loader, DFU would be quite
handy for that.
