[PATCH v1 0/3] hw/arm: xlnx-zcu102: Disable unsupported FDT firmware nodes

[Edgar E. Iglesias]

From: "Edgar E. Iglesias" <address@hidden>

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
