raspi0 machine leads to kernel panic of latest raspberry pi os kernel
Loading the kernel from the latest raspberry pi os image leads to this kernel panic running QEMU emulator version 6.0.0. The same happens with bcm2708-rpi-zero.dtb and also with older kernels.
$ qemu-system-arm -M raspi0 -kernel kernel.img -dtb ./bcm2708-rpi-zero-w.dtb -append 'earlyprintk earlycon=pl011,0x20201000 console=ttyAMA0 loglevel=8' -nographic -m 512M
