Should we delete support for NOMMU? As you say, it doesn't get much
testing, or presumably usage. I have this quote from #m68k a couple of
years ago...
: I looked at nommu very briefly when I had my 68000 board on the bench
: but didn’t get anywhere. Also didn’t try particularly hard. I think
: you are better off with fuzix or OS9 if you want something unixy.
(i suspect Zephyr would also be good, but it doesn't support m68k, just
arc, arm, arm64, mips, openrisc, renesas rx, riscv, sparc, x86 and xtensa)
