I have the same problem. imx8mmevk does not boot with Yocto Dunfell. Booting stops at "PCIe PLL lock timeout" or "Initialized imx-drm 1.0.0 20120507 for soc@0:bus@32c00000:display-subsystem on minor 0". I tried booting from MMC and from NFS, and neither work.

Do you have a revB board?

If so, please use imx8mm-evk-revb.dtb instead as there is a difference
between revB versus revC that is related to the PCIe clock source.

From arch/arm64/boot/dts/freescale/imx8mm-evk-revb.dts:

/*
* External OSC is used as PCIe REFCLK on RevC board.
* Use the -revb.dts file to distiguish the different
* HW design.
*/
&pcie0{
ext_osc = <0>;
status = "okay";
};

Could U-Boot load the correct dtb for the board revision?
