Hi All,

As many of you are aware we are starting to implement some new OPAL
firmware tests into the Firmware Test Suite
(see a previous post about a new feature recently added for OLOG ->
https://lists.ozlabs.org/pipermail/skiboot/2016-April/003121.html ).

An additional new firmware test has been added for the OPAL device tree
"Add base device-tree validity checks".

While running this check today we surfaced the following failure from dtc:

Thjs was run on the following code levels:

*CL OPAL skiboot-5.1.9-ada75ff
*OS Linux 4.4.0-21-generic
