Cannot compile device tree blob due to missing node/label

I'm trying to create a petalinux image using the petalinux SDK. After I start a build I get an error when the process tries to build the system.dtb The error is "(phandle references): Reference to non-existent node or label "ps7_scugic_0" - which is relayed twice. I believe this is some sort of interrupt device used in the ZYNQ SoC and is visible and mapped in the xml file used to generate parts of this build. How can I create this node? Do I have to edit the dts and dtsi files?
