ok i'm looking up the boot sequence stuff, this is from S5PC100 but
i'm pretty much guessing that s3c6410 is the same: it's the data at
the _end_ of the partition that gets loaded.

sooOoooOOO... hmmm... there are a couple of ways of doing this...

the first is to create a sort-of hybrid flasher and u-booter.  1st
partition FAT with the zImage_dt etc. etc. in it 2nd partition _right_
at the end, basically a copy of the NAND partition... lemme see if i
can set that up.


2.2 FUNCTIONAL SEQUENCE
Full booting sequence in BL0 is as follows,
1. Initialize the PLL & Clock setting with fixed value
2. Initialize the stack and heap region.
3. Initialize the Instruction Cache controller.
4. Load BL1 from the booting device to iRAM.*
5. If secure booting is enabled, execute integrity check.
6. If integrity check passes, then jump to 0x34010.(First 4word is reserved)
7. If integrity check fails, then it stops.
*
  NOTE1. In case of SD/MMC, iROM code load 9KB at 0x34000 from end of
memory device.
