Rpi-firmware on RPI4B cannot find devicetree on boot #8

When the RPI4B board is booting, the rpi-firmware knows based on the hardware version which devicetree to load. The firmware looks for a devicetree named bcm2711-rpi-4-b.dts , but once the vfat partition only contains the CM4 devicetree bcm2711-rpi-cm4.dts, the rpi-firmware cannot find the devicetree and it hangs.

So let's add support for the RPI4B so that we can use the br2rauc in it :)

Agreed!

I am working on adding support for more than just the CM4 based on how Buildroot handles the RPi boards. I am currently just targeting 64-bit builds for the CM4 and RPi 4B, but it should be fairly straight-forward to support other RPi boards in the same manner.

RPi 4B support added with commit: f8b8dff09ac7afaaaf3c1fc8236209378df3fb51
