[PATCH 0/3] Add initial Milk-V Duo S board support

[Joshua Milas]

This adds an initial device tree for the Milk-V Duo S board
with support for reading from the SD card and network over
ethernet. This is continued work from Michael Opdenacker's
v6 series [1] on the ARM64 and RISCV side. It has been tested
with both ARM64 and RISCV64.
