Hmmm. It seems like a good idea for COPYING to be updated to be explicit
re: why that exemption is there, to avoid future confusion.

I assume the requirement for GPLv2+ only applies to new code written for
U-Boot, not existing code that's being taken from or derived from some
other GPLv2-only project?
