Iglesias" When users try direct Linux runs on the ZynqMP models without enabling EL3 (and using appropriate FW) they run into trouble because the upstream kernel device-tree has EL3 based firmware nodes by default. PSCI firmware nodes work because we emulate the firmware in QEMU. This series avoids that problem by disabling firmware nodes that the machine cannot support due to lack of EL3 or EL2 support. This means we can now (without manually editing DTBs) run the following in a current Linux tree: qemu-system-aarch64 -M xlnx-zcu102 -m 2G -dtb arch/arm64/boot/dts/xilinx/zynqmp-zcu102-rev1.0.dtb -serial mon:stdio -kernel arch/arm64/boot/Image -initrd zu-rootfs.cpio.gz -append rdinit=/bin/sh Cheers, Edgar ChangeLog: v1 -> v2: * Constify compat in qemu_fdt_node_path().
