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 non-PSCI firmware nodes by default. PSCI firmware nodes work because we emulate the firmware in QEMU. This series avoids that problem by disabling zynqmp-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 Edgar E.
