Hello Segher

  Thanks for your comments.

I think that they work pretty well. Unfortunately, since
4b08e149c0e02e97ec49c2a31d14a0d3a02f8074 all the partiton must be
named "partition"

This wont be very flexible. With the device tree aproach we can define
partitions not only for the full flash, but also for two partitions
merged, a partition inside a partition....

Are you sure? This is what I get if I try to compile a device tree
with two partitions with the same name starting at the same address.

$ arch/powerpc/boot/dtc -O dtb -b 0 -p 1024

Sorry, I dont understand want you want to say here.

You choose :)
