similar to: [RFC] remoteproc: Add support for host-side (reversed) vrings

Implement the vringh callback functions in order to manage host virito rings and handle kicks. This allows virtio device to request host-virtio-rings. Signed-off-by: Sjur Br?ndeland <sjur.brandeland at stericsson.com> --- Hi Ohad and Rusty, This v2 version is simpler, more readable and verbose (+50 lines) compared to the previous patch. This patch probably should to go via Rusty's

From: Sjur Br?ndeland <sjur.brandeland at stericsson.com> This driver depends on Rusty's new host virtio ring implementation, so this patch-set is based on the vringh branch in Rusty's git. Changes since V1: - Use the new iov helper functions, and simplify iov handling. However this triggers compile warnings, as it takes struct iov while kernel api uses struct kiov - Introduced

Currently a host kick error is silently ignored and not reflected in the virtqueue of a particular virtio device. Changing the notify API for guest->host notification seems to be one prerequisite in order to be able to handle such errors in the context where the kick is triggered. This patch changes the notify API. The notify function must return a negative int return value in case the host

rproc_virtio_dev_release will be called iff virtio_device.dev's refer count became to 0. Here we should check if we call device_register or not, if called, put vdev.dev, and then rproc->dev's cleanup will be done in rproc_virtio_dev_release, otherwise we do cleanup directly.

rproc_virtio_dev_release will be called iff virtio_device.dev's reference count drops to 0. Here we just put vdev.dev, and then rproc->dev's cleanup will be done in rproc_virtio_dev_release.
