Change subject: fixup! Convert flashrom to git ......................................................................
Patch Set 1:
Scratch that. -U is pretty old, this fixup is completely unrelated to the commit it fixes up?
Well, not completely completely. In my initial patch that included the version string and upcache it was also changed to -u and I still think it's a good and tiny change.
I don't have *any* reservations regarding backward compatibility of this script's parameters because I bet no one but the makefile is using it yet and it simply does not make sense to have an upper-case parameter in its current form so there is really no reason to NOT change it IMHO even if it seems "unrelated" or useless. I don't see how a -2 would be warranted apart from expressing anger about the extensive bike shedding ;)
