MT2712 is a SoC based on 64bit ARMv8 architecture.
MT2712 share many HW IP with MT8173. This patchset was tested
on MT2712 evaluation board, and boot to shell ok.
This series contains document bindings, device tree including
interrupt, uart.

This adds dt-binding documentation for Mediatek MT2712.
Only include very basic items: cpu, gic and uart.

You may want to dual license this. Not sure what the rest of Mediatek
dts files do though. Also, you can use SPDX tag here if you want.

Both of these have a way to be expressed in DT. For the initrd, the
bootloader should be setting the address and size anyway.
