Microcode is actually something different -- it is the glue on top of the lowest levels of hardware to create the "native" machine language instruction set. Some firmware is microcode and some is not. In many cases, microcode can't be "uploaded" at all (though that isn't the case with Intel CPUs). Also, nothing actually limits firmware to "just" driving the hardware. Entire Linux distributions are loaded as firmware in some cases.
