[PATCH v6 06/25] riscv: qemu: Add devicetree files for qemu_riscv32/64

Simon Glass sjg at chromium.org
Thu Dec 2 16:59:00 CET 2021


Add these files, generated from qemu, so there is a reference devicetree
in the U-Boot tree.

Split the existing qemu-virt into two, since we need a different
devicetree for 32- and 64-bit machines.
