UEFI is free software, released under a BSD license. Most of the underlying platform initialisation code is non-free, and most shipping implementations of UEFI are non-free. Coreboot can be shipped under GPLv2, and so the overwhelming probability is that many vendors would ship it in a manner under which you could never exercise any of your freedoms.
