The file arch/arm/include/asm/mach-types.h comes from the Linux kernel and contains a number of CONFIG_ symbols that we have no control over nor do we wish to do anything with. Ignore that file and re-generate the whitelist.

I had also noticed that more than 1000 CONFIG symbols come from this header.
How many boards actually need mach-types.h? Can we remove the header entirely?
At issue is that CONFIG_MACH_TYPE (which will require a little thinking about how to migrate) is not something that can be up and removed. We support booting old Linux and we support booting non-Linux OSes that also make use of the old bd struct.
Something I had done half an experiment on at some point, and forgotten about, was syncing only the MACH_TYPE_xxx values as the entire rest of the header contains logic we don't need. I'll give that a whirl and report back.
