Any idea what it might take to get > qemu back to working ? Driver talks through ATF to PMU unit(microblaze). I don't think A53+MB concept is working with mainline qemu. But crash is too hard. It should be no response from PMU and then this panic. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/firmware/xilinx/zynqmp.c?h=v5.5-rc1#n728 Edgar: can you please comment this?
