Build on Raspberry Pi 5

[frapell]

I had a Raspberry Pi 3 working as an RFM69 gateway for about 2 years now, and I got a Raspberry Pi 5 to upgrade to (Basically in order to be able to run OpenHab in a more recent version), and I cannot make mysgw work...

I basically copied the work done in #1364 to get the RPi4 working (Only the Makefile and configure files). and I get this

# ./configure --my-transport=rfm69 --my-is-rfm69hw --my-rfm69-frequency=915 --extra-cxxflags="-DMY_DEBUG_VERBOSE_RFM69"

[SECTION] Detecting init system.
  [OK] Init system detected: systemd.

Running make works fine and I do get a bin/mysgw compiled, however when running it I get this

# ./bin/mysgw

Oct 06 20:03:26 DEBUG RFM69:RSB

I suspect there are maybe changes needed in the BCM driver? however not sure where to get that... Needless to say, the RFM69 module works perfectly in the Raspberry Pi 3, so no issues with the hardware...

Any advice or pointers on how to make this work? are there plans to making this work in the rpi5?
