From: Peng Fan <peng.fan@xxxxxxx>

V7:
patch 3/7: use dev_err, and R-b from Mathieu
patch 4/7: Add comment when "num_pd <= 1", add R-b from Mathieu
patch 5/7: Typo has->have, add R-b from Mathieu
patch 6/7: add detach hook to free the mbox. As wrote in the patch commit log,
imx_rproc_xtr_mbox_init is called both in probe and attach hook to resolve
mbox defer probe, so there is check in imx_rproc_xtr_mbox_init.
Moved imx_rproc_free_mbox out from parition notify to detach hook
patch 7/7: since detach hook moved to patch 6/7, so only enable recovery feature.

V6:
Two changes are made:
1.
In V5, patch 3 has a wrong logic in imx_rproc_put_scu, see [1], however
patch 4 fixed the wrong logic, as below:

- if (!imx_sc_rm_is_resource_owned(priv->ipc_handle, priv->rsrc_id))
- return;
+ if (imx_sc_rm_is_resource_owned(priv->ipc_handle, priv->rsrc_id))
+ return imx_rproc_detach_pd(rproc);

In V6, patch 3 fixed the wrong logic, drop the fix in patch 4. And patch 4
changed as below, because put scu not has return value.
imx_rproc_detach_pd(rproc);
return;

2. Include patch 7/7 to enable attach recovery, because the attach recovery
feature has been supported in remoteproc core.
