Avoid warning about dcbf, icbi first argument.

as(1) is not quite happy when RA=0 argument to these instructions is
spelled as %r0 and emits a warning. Spell that argument as 0 to
placate it. Same object code is generated.

Mark local-only function as static to save space.

Allow ppc601 to boot off hard disk

ANSIfy another 1261 function definitions.
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.

Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

Fix ofwboot to deal with larger kernels. Rather than loading at
0x6?0000, load at 0xe00000. This gives us room for around 13 MB of
kernel, as opposed to the current 5 MB (0x600000 - 0x100000).

No changes to load-base or real-base are needed due to this change,
though machines that needed specific OFW settings before (OF 1.x
and 2.x) this change still need those settings.

Partially revert revision 1.25 -> 1.26 of ofwboot/Makefile & friends.
We do not need to distinguish between where ofwboot and ofwboot.{elf,xcf}
load; they are both fine loading somewhere other than load-base.

Reorganize the way powerpc port install machine specific headers.
Use <powerpc/oea/bat.h> exclusively and remove <machine/bat.h> and
<powerpc/bat.h>. Remove unneeded <machine/cpufunc.h>. To insure
1:1 correspondence of <powerpc/FOO.h> to <machine/FOO.h> include
"../../powerpc/include/Makefile" in "arch/FOO/include/Makefile".
Incororpate <byte_swap.h> into <bswap.h> and then byte_swap.h

Make this play with gcc 3.3. Add -ffreestanding. Cleanup bootxx.

Convert to register prefixes. Use ANSI string concatenation for
multiline asm strings.

minor cosmetic tweaks:
- put \r\n before OF_open message
- use '0' + i % 10 instead of 'A' + i to print the read block number

Fixes from Bill Studenmund and Allen Briggs:
- setup a 32KB (+32byte) stack, instead of 4KB stack
- cache flush: use _start instead of 0x4000, and flush 2k instead of 1k

Features (by me):
- implement:
OF_write() (and grab "stdout" from "/chosen")
putstrn(s,n) using OF_write(); write string s of n bytes long
putstr(s); write fixed-sized string s
putc(c); write char c
- add some useful messages which output the status of loading the
stage 2 bootstrap (which is usually ofwboot)

This code now works on Bill's Beige G3!

Adjust how we set up our stack. According to the ABI, we store the
return pc address at (r1). So don't initialize r1 to be outside our
stack area. Scooted it in 16 bytes to help alignment.
