Well, as I understood from Russell, the main purpose of this "cut down"
is to make "du -s linux/arch/arm" smaller, because there is no real need in
all those boards listed in mach-types.h unless there is a support for them
in mainline Linux kernel.
Nevertheless the real ARM registry remains untouched - meaning that all
board ids remain the same and no board is removed from the registry.
This is the place where U-Boot board support diverges from Linux...
Are we obliged to follow the Linux mach-types.h?
Can't we just adopt Russell's "cut down" script to boards supported by U-Boot?
Or will it harden the mach-types.h future updates?
Have you thought of getting rid of mach-types.h completely?
Making every board define its ARM registry id can work and will
eliminate the need for mach-types.h update every couple of months.

Have you checked that none of the removed boards are in U-Boot tree?
Because if there are some, then their build will be broken...
And have to be fixed by... say a #define MACH_TYPE_* <id>
in a board_config file.
