than the first one on a controller, and work for secondary
controllers.
Due to the prom not having nodes for each disk, but a catch-all one,
we have to iterate over each device, trying to open it to determine
whether it is actually present.
Since probing this way takese some time (and spews some spurious
warnings), it should maybe be short-circuited if we use the
device we were booted from.
Implement lazy device probing, and correct slice/partiniton
handling in the ofwd_open() code. With this, I can now actually boot
a kernel from disk, and the loader does not create unnecessary
delays.

- Remove change for my local configuration that slipped in with
the last commit; I am having problems booting when multiple SCSI
disks are attached, so I will change this part as soon as I find
a solution, anyway.
- Remove two constants that were needed in conjuction with the
NetBSD disklabel header. Use the FreeBSD equivalents.
To boot from NetBSD/sparc64 partitions, define LABELOFFSET to
be 128.
- Do not use the complete open firmware path to filter out cdrom drives.
No path containing "cdrom" is detected as a disk now.
- Simplify some code.
Firmware.
- Add a temporary disklabel header to boot off a NetBSD/sparc64
partition. This file can be deleted when we have got a FCode
bootblock.
The disklabel header was obtained from NetBSD.
As of this patchset, the loader builds (under NetBSD/macppc), boots, interacts
and talks to BOOTP/NFS servers.
(main.c was moved from boot/ofw/libofw to boot/ofw/common but has no revision
history)
