Hi Fabrice,

Thanks for sending this patch.

I am also interested in getting imx7ulp evk supported in Buildroot :-)

An important step that is missing is regarding the M4 firmware.

We should probably put the M4 firmware into the the rootfs and explain
the commands to flash the QSPI with the M4 firmware.

Please see Thomas' feedback when an earlier attempt to add support for
this board was made:

Is this option really needed?

Thanks

 Actually, Fabrice's mails don't make it to the list. Are you subscribed?
