imx-mailbox.c Kernel driver Yocto Kirkstone missing imx7d-pico device. How to implement?

[neuberfran]

Hi,

https://www.youtube.com/watch?v=NFyEJXIpq4E

According to the video above, I already have Remoteproc on this device and now I want to get something like /dev/ttyRPMSG in UserSpace. To do this, I need to change my app/Zephyr/m4 side and put shared memory and ipm (mu  in this case)

Since then I have kernel panic: https://gist.github.com/neuberfran/15cfb8c9e4dd8b940408862fccc02946

Why I can't see fsl,imx7d-mu (Or fsl,imx7-mu, Or fsl,imx8mp-mu)
in ../kernel-source/drivers/mailbox/imx-mailbox.c ??? (Photo issue_111)

How to implement this?
Could this be the cause of my kernel panic?
