This ought to improve greatly with 64 bit ARM, where Red Hat are pushing for everything to support UEFI booting and ACPI for hardware description. A single upstream open source kernel should [eventually] be able to boot on every aarch64 machine, even ones that have not been seen before.
UEFI should be an improvement in this respect, but there's really no fundamental benefit to using ACPI rather than DTB for hardware description.
