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.
