To: qemu-devel
From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com>
Add a virtual Xilinx Versal board.
This board is based on the Xilinx Versal SoC. The exact
details of what peripherals are attached to this board
will remain in control of QEMU. QEMU will generate an
FDT on the fly for Linux and other software to auto-discover
peripherals.
