I was thinking at this over the weekend, and I came to the following

 - we need some improvement on the fixup we already have in the
   partition parser. We cannot ignore the fdt produced by U-Boot - as
   bad as it is.
 - the proposed fixup is fine for the immediate need, but it is
   not going to be enough to cover the general issue with the U-Boot
   generated partitions. U-Boot might keep generating partitions as direct
   child of the nand controller even when a partitions{} node is
   available. In this case the current parser just fails since it looks
   only into it and it will find it empty.
 - the current U-Boot only handle partitions{} as a direct child of the
   nand-controller, the nand-chip is ignored. This is not the way it is
   supposed to work. U-Boot code would need to be improved.

With all of that said I think that Miquel is right
