This change is not worse than change in .config, as there is no
guarantee of order of loading NAND and PROM maps.

I just looked at original 2.4 kernel. There were:
PROM EN-JP as "Filesystem", bootloader not mapped
NAND partitions as "smf", "root", "home"

This is an output of cat /proc/mtd on vendor's 2.4.20.

dev:    size   erasesize  name
mtd0: 006b0000 00020000 "Filesystem"
mtd1: 00700000 00020000 "smf"
mtd2: 02b00000 00020000 "root"
mtd3: 04e00000 00020000 "home"

We never were compatible:

Guessing from "file" output, EN-JP partition is just a file, not a
filesystem. I am OK with keeping of name "Boot PROM Filesystem" and
calling the new partition as "PROM Bootloader", but EN-JP in the name
cleanly describes the surprising contents. Adding bootloader data
partition has probably a single use case: Being easily able to grab
the PROM contents for the emulator.
