Is it worth grabbing the info from u=boot and documenting it here
(it's not documented other than in the hardkenel U=Boot source)?

I can send you the info, or you can see it in
https://github.com/hardkernel/u-boot/blob/odroidxu3-v2012.07/board/samsung/smdk5420/lowlevel_init.S
at symbol nscode_base near line 104
