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
