Updating your e-mail address, sending Ack or Nack replies to patches
for the architecture, and possibly sending pull requests to Linus
would be entirely up to you.

With neither you nor Suncore showing any activity, how is the kernel
community supposed to know if anyone maintains the architecture ?
Your e-mail pointing to a domain which no longer exists doesn't really
show much engagement.

Similar, if you _don't_ maintain the architecture anymore, it would be
prudent to let the community know by submitting a patch removing yourself
as maintainer.

The main concern is that the architecture appears to be un-maintained in
practice. We don't know if the code even compiles, much less if it works
on any target hardware. We'll see if that situation changes.
