i3c on Qemu

Hi all;

With ast2600 and the nuvoton 8xx, we're seeing the introduction of i3c and
I was curious if anyone on this list was already working on it for Aspeed
or Qemu in general.

I have submitted an initial commit for I3C with ast2600.
However, this isn't a real I3C model, and it is just good enough to
bring Aspeed SDK image up.

Thanks,

Thanks, I saw that and I think it probably fixes our bootloop issue when
i3c is enabled.  My team will be working actively on real i3c support in
the coming months as we continue building support for the next Nuvoton SoC
and the ast2600.

What kind of devices are you using ?

Thanks,

In terms of what i3c devices are going to be attached?  We are hooking up
something more complex, that I'm not sure I can describe or upstream.
Presumably we'll be able to find some device that can be upstreamed with
the support, beyond just the SoC IP blocks.

Please let us know if you need some help on ast2600-i3c.
