Use proper signedness and exact-width interger types.

Fix stupid botches in previous.

Use a proper device unit number if a unit number or non-default device
is specified on the boot command.

Use booted device unit if no unit number is specified on boot command.

Bump version to denote a visible change.

Remove unused declarations.

Add support to pass boothowto and bootdev info from bootloader to kernel.

Bootloader side changes:
- make boot command parse boothowto flags (-ads etc.)
- pass boothowto and bootdev info to the kern

Add support to pass boothowto and bootdev info from bootloader to kernel.

Bootloader side changes:
- make boot command parse boothowto flags (-ads etc.)
- pass boothowto and bootdev info to the kernel via %d7 and %d6
as the old 4.4BSD/luna68k kernel expected
- remove unused and now unnecessary "howto" (how_to_boot) command
- export and tweak make_device() in devopen.c to prepare bootdev info
- remove unused and commented out get_boot_device()

Reorgenize boot device configuration. The idea is taken from OpenBSD/luna88k.

- remove kernel-like autoconfiguration to probe bootable devices
- initialize SCSI and Ethernet controllers statically

Reorgenize boot device configuration. The idea is taken from OpenBSD/luna88k.

- remove kernel-like autoconfiguration to probe bootable devices
- initialize SCSI and Ethernet controllers statically instead
- reorganize device softc structures per autoconf removal
- probe and print all SCSI disks (but don't assign unit numbers)
- make sdopen() to recheck the device and allocate softc dynamically
- use controller number and SCSI target ID (ctlr * 10 + id) to specify
the boot disk on the "boot" command arg
- bump version to denote changes

Now bootloader works as the following:

Pull more cleanups from OpenBSD/luna88k:

- remove unused declarations
- rename struct scsi_fmt_cdb to scsi_generic_cdb

Pull more fixes from OpenBSD/luna88k:

- Bring getline() - a.k.a libsa gets() with a prompt prefix - in par with libsa
gets(), featurewise; this means support for ^u to clear the input.
- constify

Pull more fixes from OpenBSD/luna88k:

- accept empty controller and partition numbers, as well as empty filenames,
and use defaults (0, 0 and "netbsd") instead of complaining the boot path
is in

Pull more fixes from OpenBSD/luna88k:

- accept empty controller and partition numbers, as well as empty filenames,
and use defaults (0, 0 and "netbsd") instead of complaining the boot path
is invalid
- move a macro where actually necessary

Also bump version to denote the user visible change.

Check netboot and set proper default boot device.
Also bump version.

Whitespace cleanup.

Add support for "await key" to abort autoboot and get boot menu.
Also add command help. Bump version.

Remove unused bmcintr() function.

Add UFS2 support. Also bump version.

Enable and add ls command for ufs.

Fix drivers to make secondary SPC SCSI on LUNA-II work properly.
Also bump version.

Now we can load a NetBSD kernel from external SCSI disks on LUNA-II.
(and netboot on LUNA-II also works)

Add netboot support.
Based on ews4800mips, mvme68k, and x68k standalone drivers.
Also bump version.

Tested on LUNA-I.

XXX: We really need proper documents about libsa APIs.

Check cputype and set machine type (LUNA-I or LUNA-II).
Tested on only LUNA-I for now.

First cut at NetBSD/luna68k native bootloader.

Based on 4.4BSD-Lite2/luna68k "Stinger" loader revision "Phase-31"
http://svnweb.freebsd.org/csrg/sys/luna68k/stand/
and MI libsa glue stuff are taken

http://svnweb.freebsd.org/csrg/sys/luna68k/stand/
and MI libsa glue stuff are taken from hp300 etc.

Tested on LUNA-I and old DK315C SCSI disk drive.

LUNA's monitor PROM can load only an a.out binary in 4.3BSD FFS partition
(i.e. created by "newfs -O 0") on disks with OMRON's UniOS disklabel,
but now we can load an ELF kernel in root partition via this bootloader.
(See luna68k/disksubr.c for details of UniOS label)

TODO:
- LUNA-II support (check 68040 to adjust cpuspeed for DELAY())
- secondary SCSI support for LUNA-II
- netboot via le(4) (should be trivial)
- support boot options on bootloader prompt
- bootinfo (passing info about booted device and kernel symbols)
- support "press return to boot now, any other key for boot menu" method
like x86 bootloader (needs cnscan() like functions)
- tapeboot (anyone wants it?)
