[PATCH 0/9] remoteproc: imx_rproc: support i.MX8/8M/7ULP

[peng . fan]

From: Peng Fan <peng.fan@xxxxxxx>

This patchset aim to replace NXP vendor imx_rpmsg.c driver.

This patchset is tested with Loic PALLARDY's patch
"remoteproc: add support for co-processor loaded and booted before kernel"
https://patchwork.kernel.org/patch/11265869/,
and inspried from st's remoteproc early boot support.
Since Loic's patch is still under review, just expect your comments :)

Patch [1,2]/9: dt-bindings convert to json and new SoC support
Patch 3/9: skip firmware load when recovery. To i.MX8, firmware is not
           handled by Linux.

Patch [4-9]/9: i.MX specific part to support rpmsg/virtio with mbox.
      because NXP release image not have resoure table, so add resource
      table in dts

My test dts diff for i.MX8QXP MEK, but I have tested this patchset
for i.MX8QXP MEK, i.MX8MM EVK, i.MX7ULP EVK:
