it looks like newer interface definitions
specify using "guest native endianness" for Virtual Queue data. So
I think the same should be done for RPMsg instead of enforcing LE?

It is hard to imagine use-cases where 512 buffers would really be
needed, whereas 512 bytes per buffer might be too little. Change this
to use 16 16KiB buffers instead.

The SOF ADSP vhost driver consists of two parts: a sound and a vhost
part. This patch implements the vhost part of the driver. It handles
QEMU communication with the vhost misc device and virtual queues to
any VirtIO RPMsg guests.

No, RPMSG_VIRTIO is used on the guest side, VHOST_RPMSG (as well as
all other vhost drivers) on the host side.
