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"
