I wonder... how do I create an read-only environment variable in the
board code? The variable should be created before env0 is mounted, but
shouldn't be destroyed by mounting env0.

I'm thinking of some
BAREBOX_PARTITIONS="0x34000 at 0(barebox),0xC000(barebox-cramfs)".
It must be able to survive saveenv followed by a barebox update (which
may change the cramfs address and size, i.e. the value saved in env0
must be discarded).
