The MIPS ports looks like it are based on OpenJDK6 and Hotspot hs14, the 
same hotspot used in the IcedTea6-1.8 release.

In order to merge the MIPS port with IcedTea6 you will have to update 
the MIPS port to be compatible with the same hotspot used by IcedTea6 HEAD.

The IcedTea6-1.8 release branch uses the same hotspot version hs14 as 
the MIPS port so a merge at this point are easy but its too late to go 
in because the release branches do not accept new features.

The IcedTea6-1.9 release uses hotspot version hs17.
The IcedTea6-1.10 release uses hotspot version hs19.
The next IcedTea6-1.11 release are currently based on hs20, HEAD.

For a merge to happen its required to update the MIPS port to hs20 and 
merge it against the current development HEAD at:
http://icedtea.classpath.org/hg/icedtea6

You can track when the release branches forked from the IcedTea6 tag list:
http://icedtea.classpath.org/hg/icedtea6/tags

I suggest you start by first checkout the IcedTea6-1.8 branch-point
http://icedtea.classpath.org/hg/icedtea6/rev/9420faca6468
and merge at this point.

Then pull in the IcedTea6-1.9 branch-point merge and fix any issues when 
using hs17.
Then pull in the IcedTea6-1.10 branch-point merge and fix any issues 
when using hs19.
Then pull in the IcedTea6 developement HEAD, merge and fix any issues 
when using hs20.

When this are done please send in a patch.
