Ok, that puts some light into this. Please make sure your partitions are
aligned to eraseblock boundaries, usually 128k. so:
addpart /dev/nand0 512k(barebox)ro,128k(bareboxenv),3M(kernel),-(root)
barebox currently does not enforce this, it's probably time to change
this. Unaligned partitions are fine, but the partition code should mark
them as readonly.
Currently we have no way of passing the eraseblocksize through to the
partition code, so it's not trivial to enforce alignment.
