- Determine and remember if we are a floppy.
- Workaround for what is apparently a firmware bug - ignore the sector
size returned by the device. On my Firepower's floppy, block-size
is the same as max-transfer, which causes Lossage.
- Don't read the disklabel on a floppy; do what the ISA floppy driver
does, which is assign the entire disk to each "partition", although
we do not deal with the density stuff.
- FIREPOWERBUGS -> FIRMWORKSBUGS
- Some general cleanup.
- Make setregs() conform to the PowerPC SVR4 ABI, plus one NetBSD
extention (for ps_strings).
- machine == powerpc, not PowerPC.
- Set up machine vector for OpenFirmware.
- Nuke the msgbuf for now; it's not mapped correctly.
- Add missing casts in some asm() directives.
- Enable PSL_RI earlier, and do *not* disable it in fake_spl(), since it
is needed for page faults.
- Some general cleanup.
- Clean up symbol goop - use macros in asm.h where appropriate.
- Add, correct, and generally clean up comments.
- Properly align save areas and temporary stacks.
- Fix the 603 tlb reload code.
- Fix several bogus constants and modifiers.
- Some stylistic changes.
on to the kernel. The boot program passes a boot args string plus
additional information like so:
/pci/scsi@3/disk@0,0:1/netbsd -s<NUL><esym><tag>
The post-<NUL> values are:
<esym> end of the kernel symbol table (32-bits)
<tag> machine type tag (32-bits)
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).
