Looks like Norm said he fixed this. Also, in general people should
never need to
build serverwiz themselves. They can just download the jars from the

In the past we've seen where the person who own the MRW XML, who is
of the firmware group, is slow to bring an XML fix through a pull
github.com/open-power/<system>-xml. With a patch, we can make a fix
own repository without having to check in the full <system>.xml which
exist inside the openbmc repositories. It also allows the fix to remain
MRW XML updates if they don't fix the desired thing. Additionally, it
can add an easier
way to phase in new code that uses new XML, first by using the patching
then later updating the real XML.

Sounds reasonable, though I don't personally have any experience with
so it will be slow going for me.

Sure, I can add that to the list.
