This series adds basic support for Apple's M1 SoC to U-Boot.
This builds a basic U-Boot that can be used as a payload
for the m1n1 boot loader being developed by the Asahi Linux
project.

The goal here is to privide an UEFI interface on these machines that
allows booting various open source OSes.  This initial series provides
support for the serial port, framebuffer and the USB 3.1 Type-C ports.
It can boot a support OS (e.g. OpenBSD/arm64) from a USB disk.

This version attempts to address most comments.  It doesn't add a
proper WDT/sysreset driver yet since I prefer to do that once the
device tree bindings for that have been ironed out.


ChangeLog:

v2: - Add IOMMU uclass and use it for the DART driver
    - Cut back DART driver to only support bypass mode
    - Rework the S5P serial support to use more DT stuff
    - Update preliminary device trees

Please do this soon. We can easily change a compatible string later if
needed, but having strange code in there provides a bad example for
others.
