The advantage of putting the kernel/u-boot/at91bootstrap in the
machine file, is that I can make a copy of a machine file to another
file, change the version of the include file and build.

I dont have to change any files, so nothing existing breaks.

Once everything is tested, I can just replace the old machine file
with the new file and check in.
