I have been able to get Xen+dom0+domUs booting. Tested with Xen 4.12 and Linux 4.19.y (Raspberry Pi linux tree + a couple of patches). Please see [1] for build instructions and limitations. Andre - it appears that we each independently came up with a printk configuration [2]. With this series, you'd no longer need to remember the base address, just do CONFIG_EARLY_PRINTK=rpi4.
