imx8mm, u-boot 2024.04, display issue

Hello,

I'm facing an issue with the display driver when migrating from u-boot 2023.04 to 2024.04.

Before booting the kernel, u-boot remove the display if it was probed during the boot.

With 2024.04 it crashes at this step whereas it is OK with 2023.04.

It is also OK if the display is not probed during boot process, because obviously there is not need to remove it, but it confirms that the issue is related to the display.

Someone knows if there is something change in u-boot 2024.04 related to the handling of the display ?

Thanks for your help.

You can take as base the uboot from NXP, also you can take this appnote:
