#     
#     Pull ARM Apple M1 platform support from Arnd Bergmann:
#      "The Apple M1 is the processor used it all current generation Apple
#       Macintosh computers. Support for this platform so far is rudimentary,
#       but it boots and can use framebuffer and serial console over a special
#       USB cable.
#     
#       Support for several essential on-chip devices (USB, PCIe, IOMMU, NVMe)
#       is work in progress but was not ready in time.
#     
#       A very detailed description of what works is in the commit message of
#       commit 1bb2fd3880d4 ("Merge tag 'm1-soc-bringup-v5' [..]") and on the
#       AsahiLinux wiki"
