Hi Magnus,

Thanks for you reply. Please see inline:

If possible, I am willing to take this responsibility.

I support this suggestion. We already have a jdk8 MIPS64 port and we
will maintain it for a long time, so I think mips-port/jdk8 or
mips-port/jdk8u may be needed. I do have plans to upgrade our port to
the latest jdk/jdk master. Actually, I have done some research and
experiment in the past few days. However, I can't guarantee how long
it will take to get the job done.

I have one question about the name. Our port is for MIPS64, and I know
some companies are doing MIPS32 port. I am not sure whether they will
upstream their work. If yes, it is not known yet that whether the code
is merged into "mips-port/jdk11" (or jdk8, or ...)  or into different
repositories. So which name (mips-port or mips64-port) are more
suitable for the current situation?

Thank you.
