[PATCH v5 07/26] riscv: qemu: Add devicetree files for qemu_riscv32/64 |
|
Date: |
Mon, 25 Oct 2021 18:23:25 -0600 |
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.
