Initial commit of a 1-stage boot loader for NetBSD/cobalt. Only booting off
the hard drive is supported at the moment.

Always build for mips3. Use -Os instead -O2 for smallest code size.
text goes from 74608 to 63020

branches: 1.29.4;
Use ${TOOL_GZIP_N} instead of ${TOOL_GZIP} -n, and similarly
use ${TOOL_GZIP_N} -9 instead of ${TOOL_GZIP} -9n, etc.

This will pass -nT instead of just -n if the gzip program is
actually pigz.

branches: 1.28.2;
Pass the -n flag to gzip invocations.

This prevents it from embedding a timestamp in the output. We pass
"-n" unconditionally, not conditional on MKREPRO, because many other
invocations of gzip already passed the -n flag unconditionally.

eliminate use of bsd.sys.mk from Makefiles

Add empty LIBCRTI= as LIBCRT0 to build sa programs without installed DESTDIR.

XXX: probabry we should have bsd.saprog.mk or something.

branches: 1.25.2; 1.25.12; 1.25.16;
don't set MACHINE_ARCH. the CPUFLAGS/etc. is enough, and otherwise this
doesn't work with an isolated $TOOLDIR from the mipse[lb] toolchain.

Use TOOL_GZIP

Merge forward from matt-nb5-mips64.
(XXX generic kernels on raq2 die after interrupts are enabled but gxemul
works fine).

Drop bootprog_maker (formerly enabled by -M) and bootprog_date (formerly
disabled by -D) from the output of newvers_stand.sh. Change -D to the
inverted logic, so that it adds the date to bootprog_rev in ().

Change all platforms accordingly. -D is added if MKREPRO is not yes and
wasn't present before. Platforms that didn't use -D don't depend on
MKREPRO now either.

branches: 1.21.2; 1.21.4;
Introduce .WAIT into the cleandir rule for blasting the libsa/libkern/etc.
trees, because it can race with the libsa/libkern/etc. makefiles' own
cleandir rules. I think I've found all of the uses of the offending idiom...
Closes PR 43360.

branches: 1.20.2; 1.20.4;

Add support for optional Z85C30 serial console on Cobalt Qube 2700.

Link libkern last. It contains functions normally found in libgcc, so
other libraries might have references to them.

Makes this compile with gcc4 (that emits calls to __ash[rl]di3 in libsa).

branches: 1.9.10;
Don't specify the object format to pick the right endianness - the
linker already knows if it is big- or little-endian.

Ignore errors on some rm -rf's for platforms that aren't quite
POSIX compliant
and return errors on r/o source (FreeBSD) for -rf. Fixes PR#25022

Add a prompt to specify a kernel filename to be loaded on bootloader.

branches: 1.6.2;
Load the boot program at 0x80F00000 to give the boxes with just 16Mb of
RAM a chance to boot. Discussed with soren@, tested on customer's board.

NB: While acceptable as a temporary workaround since most (all?) Cobalt
hardware comes with no less than 16Megs on board, changing a kernel load
address or making a boot loader relocatable could be a better solution.

Pass some info from the boot loader to the kernel:

- Kernel image name
- Symbol table
- A flag indicating console presence (could be clobbered if not passed)

Add _rtt() entry to the boot loader code.

Include <bsd.own.mk> at the top so that machine-links are also created
on "make depend". Tested on my RaQ2, and fixes port-cobalt/23711.
While here, two more cosmetics:
- remove redundant definitions
- use NOMAN rather than setting MAN empty

Use ${HOST_SH} instead of `sh'.

If necessary, pull in <bsd.sys.mk> to get the definition of HOST_SH;
Makefiles that pull in one of (most of) <bsd.*.mk> will get this anyway.

Define LIB{CRT0,C,CRTBEGIN,CRTEND} as nothing, we don't need to link
against them.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

Add more wait after sending a setup packet since

Misc fixes to support 21041 on Qube2700:

- use a recently added pcicfgread() function to get tulip I/O address
- use cobalt model id to see if we have 21041 or 21143
(XXX maybe it's better to see PCI product ID)
- add code to reset SIA on 21041

Overhaul MBR handling (part 1):

<sys/bootblock.h>:
* Added definitions for the Master Boot Record (MBR) used by
a variety of systems (primarily i386), including the format
of the BIOS Parameter Block (BPB).
This information was cribbed from a variety of sources
including <sys/disklabel_mbr.h> which this is a superset of.

As part of this, some data structure elements and #defines
were renamed to be more "namespace friendly" and consistent
with other bootblocks and MBR documentation.
Update all uses of the old names to the new names.

<sys/disklabel_mbr.h>:
* Deprecated in favor of <sys/bootblock.h> (the latter is more
"host tool" friendly).

amd64 & i386:
* Renamed /usr/mdec/bootxx_dosfs to /usr/mdec/bootxx_msdos, to
be consistent with the naming convention of the msdosfs tools.

* Removed /usr/mdec/bootxx_ufs, as it's equivalent to bootxx_ffsv1
and it's confusing to have two functionally equivalent bootblocks,
especially given that "ufs" has multiple meanings (it could be
a synonym for "ffs", or the group of ffs/lfs/ext2fs file systems).

* Rework pbr.S (the first sector of bootxx_*):
+ Ensure that BPB (bytes 11..89) and the partition table
(bytes 446..509) do not contain code.
+ Add support for booting from FAT partitions if BOOT_FROM_FAT
is defined. (Only set for bootxx_msdos).
+ Remove "dummy" partition 3; if people want to installboot(8)
these to the start of the disk they can use fdisk(8) to
create a real MBR partition table...
+ Compile with TERSE_ERROR so it fits because of the above.
Whilst this is less user friendly, I feel it's important
to have a valid partition table and BPB in the MBR/PBR.

* Renamed /usr/mdec/biosboot to /usr/mdec/boot, to be consistent
with other platforms.

* Enable SUPPORT_DOSFS in /usr/mdec/boot (stage2), so that
we can boot off FAT partitions.

* Crank version of /usr/mdec/boot to 3.1, and fix some of the other
entries in the version file.

installboot(8) (i386):
* Read the existing MBR of the filesystem and retain the BIOS
Parameter Block (BPB) in bytes 11..89 and the MBR partition
table in bytes 446..509. (Previously installboot(8) would
trash those two sections of the MBR.)

mbrlabel(8):
* Use sys/lib/libkern/xlat_mbr_fstype.c instead of homegrown code
to map the MBR partition type to the NetBSD disklabel type.

* Deprecated in favor of <sys/bootblock.h> (the latter is more
"host tool" friendly).

amd64 & i386:
* Renamed /usr/mdec/bootxx_dosfs to /usr/mdec/bootxx_msdos, to
be consistent with the naming convention of the msdosfs tools.

* Removed /usr/mdec/bootxx_ufs, as it's equivalent to bootxx_ffsv1
and it's confusing to have two functionally equivalent bootblocks,
especially given that "ufs" has multiple meanings (it could be
a synonym for "ffs", or the group of ffs/lfs/ext2fs file systems).

* Rework pbr.S (the first sector of bootxx_*):
+ Ensure that BPB (bytes 11..89) and the partition table
(bytes 446..509) do not contain code.
+ Add support for booting from FAT partitions if BOOT_FROM_FAT
is defined. (Only set for bootxx_msdos).
+ Remove "dummy" partition 3; if people want to installboot(8)
these to the start of the disk they can use fdisk(8) to
create a real MBR partition table...
+ Compile with TERSE_ERROR so it fits because of the above.
Whilst this is less user friendly, I feel it's important
to have a valid partition table and BPB in the MBR/PBR.

* Renamed /usr/mdec/biosboot to /usr/mdec/boot, to be consistent
with other platforms.

* Enable SUPPORT_DOSFS in /usr/mdec/boot (stage2), so that
we can boot off FAT partitions.

* Crank version of /usr/mdec/boot to 3.1, and fix some of the other
entries in the version file.

installboot(8) (i386):
* Read the existing MBR of the filesystem and retain the BIOS
Parameter Block (BPB) in bytes 11..89 and the MBR partition
table in bytes 446..509. (Previously installboot(8) would
trash those two sections of the MBR.)

mbrlabel(8):
* Use sys/lib/libkern/xlat_mbr_fstype.c instead of homegrown code
to map the MBR partition type to the NetBSD disklabel type.


Test built "make release" for i386, and new bootblocks verified to work
(even off FAT!).

branches: 1.1.2;
Initial commit of a 1-stage boot loader for NetBSD/cobalt. Only booting off
the hard drive is supported at the moment.

Use macro defined in <machine/cpu.h> for cobalt_id and device addresses etc.
since <machine/leds.h> has been removed.
Also remove redundant address definitions in Makefile and local headers.
