FYI I was able to get the gateway to work properly on a 64 bit Raspberry pi 400 machine.
pi@sixfour:~ $ cat /proc/cpuinfo | grep Model && uname -a
Model : Raspberry Pi 400 Rev 1.0
Linux sixfour 5.10.5-v8+ #1392 SMP PREEMPT Sat Jan 9 18:56:30 GMT 2021 aarch64 GNU/Linux
I'm not sure if it's required, but installing the bcm2835 v 1.68 (that includes an earlier patch for pi 4) may have helped along with removing the bcm2711 flags from the configure file.

granted I have not fully tested this since I do not yet have a radio connected, but I think it went ok.

I will plop a radio in this weekend and see if it still works.
