successful build using Arm GNU Toolchain (12.3.rel1) report about bmc64

I suspect you will find the resulting build for the Pi Zero hangs with a black screen - all later toolchains have has this effect for reasons I never really bothered to examine. Builds for all other models (except 4, of course) work as expected.

Sure, all of the 3.x releases are for "Not Recommended for New Design" Pi boards. Being new to this "bare metal" scene, I won't invest much for my tinkering trying to use an old toolchain.

I am curious about the 4.x code tree on where it might be headed and figured I give this a workout, if only to use as a reference. I am infatuated with the 8BitDo Retro Mechanical Keyboard, which does not work with bmc64 v3.9, and would like to inspect further as to why/how and if ...

If anything, I can always re-make this into a VIC 20 kiosk running Mega-Cart! 💯
