- Garbage collect some cruft that doesn't apply to the ofppc port.
- Make our OFW-friendly alloc.c more like the libsa alloc.c
- Generally reduce some differences where we can between this
boot loader and the NetBSD/macppc boot loader.
- Use libsa's loadfile().
- Fix DDB symbol loading -- Add a magic number after the args string
so the kernel knows the symbols are there, provide both ssym and
esym, and make sure all these values are aligned to a 4-byte boundary.
- Add support for MS-DOS file systems.
maps standard boot flags to corresponding RB_* values
use BOOT_FLAG() in port's MD code as appropriate
as discussed on tech-kern, add new boot flags -v, -q for booting
verbosely or quietly, and corresponding AB_VERBOSE/AB_QUIET
boot flags; also add FreeBSD-compatible bootverbose macro and
NetBSD-specific bootquiet macro
for hpcmips, use new bootverbose instead of it's own hpcmips_verbose
Tested on i386, and to limited extend (compile of affected files) also for
mvme68k, hp300, luna68k, sun3.
NetBSD/powerpc boot program. Highligts:
- Rearrange a bit so that we can sanely add boot programs for
non-OpenFirmware systems.
- Add support for loading compressed kernels (for booting from
1.44M floppies).
- Add support for loading Elf kernels (Elf is the new standard format
for NetBSD/powerpc). (XXX Don't load symbols right now - the code
to do it is there, but I don't particularly like how space for the
symbol table is allocated; I will revisit this soon'ish).
