The partition size for barebox-environment and the devicetree used to be
one eraseblock only. Now it's again only one eraseblock at least for the
4k Page size variants. If one of those blocks is bad the board becomes
unusable. I think the partitions should be at least two eraseblocks.
That of course would make them quite big.

Any opinions about this?
