you have the @rock-chips.com address, so I'd guess you might even have
the better resources to find out ;-)  .

In any case, as I said I haven't looked at all at the internal storage on
my radxarock so far.

But as the rk3066 and rk3188 are so similar I've added Paweł.

@Paweł: you had uboot starting from nand on your rk3066 board, maybe you
could describe how you wrote it to the board so maybe Andy can check if
he needs to adapt anything?
