The board comes with different flash sizes with different bank widths.
That's why I decided to no put the flash entries into the tree.
We used to detect the flash size/bankwidth using the bootcs config
register (which was previously set by U-Boot). We could change U-Boot to
adjust the device tree accordingly, but we haven't done this so far,
sorry.

I think partitions shouldn't go into the default device tree, as people
may have different partitioning.
