raspberrypi cm4 devicetree missing?

[Belisko Marek]

Hello,

I'm using u-boot v2020.01 and run on cm4 model it boots fine just
report that model is unknown:

DRAM:  948 MiB
RPI: Board rev 0x14 outside known range
RPI Unknown model (0xa03140)

I checked and in later releases there is added support for cm4 but
what I'm missing is devicetree blob. In mainline commit:
561bce3522bd1df5f6b10fbae5a6ea5c0b131ff9 is set to bcm2711-rpi-cm4.dtb
but I cannot find such file in u-boot tree. My idea is to change the
console to use UART2 instead of mini uart. Thanks for clarification.

BR,

marek
