From: Andrew Jeffery <andrew at aj.id.au>
The patch adds a separate devicetree file specifically for QEMU,
integrating the Cadence GEM device which is configured with the MMIO
base and IRQ for what would be MAC2.

+Subject: [PATCH] arch/arm: Add qemupalmetto dts with Cadence GEM support
+
+Describes a machine that is as similar to the Palmetto BMC, primarily for
+running under QEMU. Relaxing the constraint of booting the exact Palmetto
+BMC hardware in QEMU allows us to integrate existing device models to expand
+the machine's capability without huge effort.
+
+In this case, the Cadence GEM controller is integrated to provide networking.
