[Qemu-riscv] [PATCH] hw/riscv/virt: re-add machine-specific compatible string to /soc/ node |
Date: |
Sun, 10 Feb 2019 21:17:26 +0100 |
Re-add the previous compatible string "riscv-virtio-soc" to the soc
device tree node to allow U-Boot and Linux to bind machine-specific
drivers to it. The current compatible string "simple-bus" is retained.
This is required by U-Boot to bind devices early, as part of the
pre-relocation driver model.
Fixes: 53f54508dae6("hw/riscv/virtio: Set the soc device tree node as a
simple-bus")
