Commit 0c10962a033 from Hervé was part of a bigger refactor series, so I 
don't think he is interested.

Now back to this board, I am having hard time to understand what it 
models. IIUC it predates the Malta board, and was trying to model a 
board able to run the first MIPS cpu when the port was added in 2005 
(see commit 6af0bf9c7c3a).
The Malta board was added 1 year later (commit 5856de800df) and models a 
real hardware.

As Aurelien acked to step down maintaining it, it seems the perfect 
timing to start its deprecation process. I'll prepare a patch for 5.0 
(unless someone is really using it and willing to maintain it).

Regards,

Phil.

Philippe, hi.

Herve told me a while ago that he does care about R4000 being
supported, as it is closely related to Jazz machines, so please
don't start any deprecation process.

Herve is the most familiar of all of us with R4000, and, for that
reason, my suggestion is to keep the patch as it is. Let me know
if you have any objections.

One alternative approach would be to merge "R4000" and
"Jazz" sections. But, let's leave it for future as an option,
if nobody objects.

Yours,
Aleksandar

I think what Hervé meant to say is he cares about the R4000 CPU 
(implementing the MIPSIII architecture). The Magnum and Pica boards 
indeed use a R4000 CPU. I also personally care about this CPU, and don't 
want it to disappear.

Here we are talking about the some Frankenstein board. QEMU aims to 
model real hardware, with the exception of the 'Virt' boards that have 
specifications. Here I can't find any. I am not against Hervé 
maintaining this file if he has some interest in it, but I think there 
are confusion and we are talking about 2 different topics.

Philippe is right.
I care about Magnum/PICA boards (which have a R4000 cpu).
I don't care about this the mips_r4k.c machine, and I think that deprecating mips_r4k.c machine is the right thing to do.

Jazz and mips_r4k machines have mostly nothing in common, except using a R4000 CPU and an ISA bus.
