[OE-core] [OE-Core][PATCH 0/9] Add MIPS release 6 ISA support

[Mark Hatle]

A few general comments.  I don't see an n32 variant implemented.  I'd suggest a
follow on patch (vs a new version) to add n32.

It looks like it's missing in the files modified by patches 6-9.

Otherwise I don't see any issues with adding the support for this new ISA.
