I don't know. If the table is wrong, we should fix it. Yes, it may
break someone, but it probably will not.

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.
