Nevertheless I really appreciate the effort you're taking to explain
this. Not just for myself either:
If bunches of bits are to be redistributed in Debian, that needs to be
done in a manner compatible with the explicit promises of the Social
Contract, regardless of whether those who package those bits for
redistribution are themselves trained electrical engineers.
So, it's important for the freedom issues to be understood by we mere
mortals who don't deal with logic boards; and that involves bridging
gaps in understanding, without requiring all of us learning everything
about each others's field :-)

I'm not disputing that. The reason these programmatic bit streams are
an issue is that if they're to be redistributed by Debian, the
recipient needs to have the guarantees of freedom as per the Social
Contract. So, it is irrelevant (for the purpose of satisfying the
contract of freedom) which particular hardware they are intended to be
loaded into, be it a CPU or a daughterboard processor.

So, it sounds like we're talking about exactly the same freedom
issues, just with a different processor involved: the PCI board's
processor instead of the motherboard's CPU.

That +IBw-raw junk+IB0- is, if I understand you correctly, instructions and
data for controlling the behaviour of the processor on the PCI chip.
How is this different from saying that the machine-code form of a
program is +IBw-raw junk for the motherboard's CPU+IB0-?
I get the impression you're saying it's different in some way other
than which processor the bit stream is destined for, but I'm trying
without success to see what difference exists that eliminates the
right of the recipient to have freedom in that work.

Understood; I'm fairly sure the distinction between which processor
these bits are intended for is clear to readers of this thread.
What I don't see is a justification for denying the right of freedom
in that bit stream for the recipient of the Debian operating system
where these bits are redistributed.
Note that +IBw-only a tiny fraction of the recipients could ever make
practical use of the source form of the work+IB0- is no justification for
denying any recipient the freedom to get that source form; we don't
accept that argument for processor code destined for a motherboard
CPU, after all.

What, then, does the chip manufacturer +IBQ- who, if I understand you
correctly, is the copyright holder and vendor of the firmware +IBQ- have
as the means of generating *new* processor firmware targeted to the
*same*, already-sold, hardware?
I would argue that that form of the work meets the definition of
+IBw-source code for the firmware+IB0-. Yes?
