Not sure about that. I was thinking of a simple script that reads Linux'
mach-types.h (or arch/arm/tools/mach-types directly) and generates the
u-boot's mach-types.h file on the fly. That way only the #define lines could
be generated, producing a less than 100k files instead of > 1MB.

The same script would read the existing mach-types.h file, scanning for
something like

/* MANUAL ENTRIES START */
#define MACH_TYPE_XYZ 4711
#define MACH_TYPE_ABC 4712
/* MANUAL ENTRIES END */

and retain lines that are still above the official limit.
A commit should show only "+" for the new official definitions and a "-"
for all automagically removed manual definitions.

Otherwise:

It essentially means one can send patches for a new ARM based board
only if the MACH_TYPE has trickled through all the instances.

This is, somehow, unpleasing:). We should not "punish" ourselves in u-boot
just because someone has invented a method to prolong time-to-market ;)
