Hi Qi,

I think there is interest in getting MIPS code upstream, but it may
take some time, since a port is a large change, and there are some
questions to resolve.  I think there are issues of maintenance, for
example.  But for process, as a start, any contributions to the
OpenJDK base must be made by signatories of the Sun Contributor
Agreement, which can be obtained here:

In the meantime, we may want to maintain a separate OpenJDK branch
that we merge from the mainline (6) regularly.  Ideally, it would be a
common tree that we use for all MIPS platforms.  Reservoir could host
that tree, if that makes sense.
