That’s the reason for the latest longer discussions related to RPI4(B) here on the list.

2 possibilities:

[1]. armstub8-gic.bin needs to be hacked further to get back compatibility to the upstream
or
[2]. armstub8-gic.bin is removed (as in most current Linux-distros(which are compatible with the upstream)),
 which needs further hacking in the fbsd-kernel(at least implement spinTables to initialize SMP).

Mark M. seems to be hoping for a possibility [3]( that we just have to change the address space of current armstubs).
I have no prove that this is  what Mark is searching for(just a GUESS) :-) Ha Ha 

By the way, thanks Mark for the 2nd gonzo-SMP-blogpost link.
