MicroBlaze V is new AMD/Xilinx soft-core 32bit RISC-V processor IP. It is hardware compatible with classic MicroBlaze processor.
The patch contains initial wiring and configuration for initial HW design with memory, cpu, interrupt controller, timers and uartlite console (interrupt controller is listed but U-Boot is not using it).
Provided DT is just describing one configuration and should be taken only as example.

xlnx,xps-intc-1.00.a driver exists in the Linux kernel but DT binding is missing. That's something what we need to work on. arch/arm64/boot/dts/xilinx/xilinx-mbv32.dtb: /axi/interrupt-controller@41200000: failed to match any schema with compatible: ['xlnx,xps-intc-1.00.a']
Public annoucement is available here if someone is interested. https://www.xilinx.com/products/design-tools/microblaze-v.html?utm_source=ma...
