It was bugs and user error.

The user error was not using the serial console. The NetBSD/arc 
installation guide says that only serial console is supported for MIPS 
Magnum.

The bugs include regressions in NetBSD. (See below.)

The other issue is that the ARC firmware didn't work properly until I 
defined one or more 'boot selections', even though none of these will ever 
be selected.

The commit log says that Herv? Poussineau used NetBSD 5.1 with dp8393x in 
the past, so I tried that.

Here are the steps I used:

./mips64el-softmmu/qemu-system-mips64el -M magnum -L .  
-drive if=scsi,unit=2,media=cdrom,format=raw,file=arccd-5.1.iso
-global ds1225y.filename=nvram -global ds1225y.size=8200
-serial stdio -serial null
-nic bridge,model=dp83932,mac=00:00:00:02:03:04

-> Run setup -> Initialize system -> Set default configurations
	800x688
	3.5 1.44 M
	No
	7

-> Set default environment
	CD-ROM
	2

-> Set environment variables
	CONSOLEIN
	multi()serial(0)term()
	CONSOLEOUT
	multi()serial(0)term()

-> Exit

Now restart QEMU. The ARC menu should appear on the tty.

-> Run a program

	scsi(0)cdrom(2)fdisk(0)boot scsi(0)cdrom(2)fdisk(0)netbsd

That doesn't work. Add a boot selection.

-> Run setup -> Manage startup -> Add a boot selection -> Scsi CD-ROM 0
	\os\nt\osloader.exe
	Yes
	\winnt
	Windows NT
	No

Somehow, that seems to help. Now restart QEMU.

-> Run a program

        scsi(0)cdrom(2)fdisk(0)boot scsi(0)cdrom(2)fdisk(0)netbsd

My initial testing shows that NetBSD 5.1 doesn't like my v2 patch series. 
I'll debug that before I send v3.

BTW, there seem to be regressions in NetBSD 8.1 compared to NetBSD 5.1. 

The 'boot' program on the 8.1 ISO just hangs.

If I use the 'boot' program from the 5.1 ISO to load the 'netbsd' 
binary from the 8.1 ISO, I get a crash:
