Well, it would be part of a driver aimed at driving the main cpu, yes, it is
not a peripheral processor, but the role played by the microcode is peripheral
to the main flow of the kernel code.

You did notice where i explained that microcode is loaded into a lower level
of the cpu, and not in the same level as the code normally runs, right ? Why
do you then deliberately misinterpret it in the above.
In particular, when a normal program is loaded, the main processing unit of
the cpu has a program counter which loads instructions into the cpu, and those
are then executed and so on.
The cpu microcode doesn't follow this selsame route, and as thus, are loaded
into a peripheral part of the cpu.

Sure, but we are speaking clasification of the the firmware blobs. We all
agree that those who are sourceless and not just plain register dumps are

Bah, you are changing topic because you don't want to admit that my
classification proposal of what we want to describe as firmware in the context
of this GR is indeed enough to remove all doubts about what we are speaking
