But apply on u-boot.git will have some conflicts. Applying: riscv: qemu: use device tree passed by prior boot stage error: patch failed: board/emulation/qemu-riscv/qemu-riscv.c:9 error: board/emulation/qemu-riscv/qemu-riscv.c: patch does not apply Patch failed at 0001 riscv: qemu: use device tree passed by prior boot stage May I ask which tree do you want to merge into mainline ? from dm tree or riscv tree ? So the merge of patch work can go smoothly.
