OK.  Put OpenBSD 7.1 on a Raspberry Pi 4.

Some bumps in the road, but I am running a Cuis image.

pkg_add   git xfce xfxe4-extras gdb bash sudo emacs ..

usermod -G operator,kmem,staff

Kicked up the memory cap in /etc/login.conf for staff.

The only large wrinkle was with an include file
  platforms/unix/vm/include_ucontext.h

I had to add a section
  #elif __OpenBSD__ && __arm64__
for the arm64 CPU.

vvv===vvv===vvv
#elif __OpenBSD__ && __amd64__
# define _PC_IN_UCONTEXT sc_rip
# define _FP_IN_UCONTEXT sc_rbp
# define _SP_IN_UCONTEXT sc_rsp
#elif __OpenBSD__ && __arm64__
# define _PC_IN_UCONTEXT sc_x[30]  /*??PC??*/
# define _FP_IN_UCONTEXT sc_x[29]
# define _SP_IN_UCONTEXT sc_sp
#endif
^^^===^^^===^^^

I also had to remove JoystickTabletPlugin from
  building/linux64ARMv8/squeak.stack.spur/plugins.int

So, things compiled, got X11+XFCE up.  Cuis image came right up.  AOK

I still don't know the proper way to get the PC from the
  struct sigcontext
defined in signal.h  and machine/signal.h.

I'm not an OBSD user, so any hinte here appreciated.

HTH,
