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