cc494d0cce Probe the keyboard if PROBE_KEYBOARD is defined instead of when `notyet'
is defined and FORCE_COMCONSOLE isn't defined.

Don't compile any keyboard probing code if PROBE_KEYBOARD isn't defined.

Makefile:
Removed -I paths.  They weren't used, and the one to /sys hasn't worked
since the source directory was moved down one level.

27253a3d9c Made the timeouts in gets() machine-independent. Use the BIOS tick
counter instead of the BIOS time call to save space.

Reworked the anti-noise timeout to avoid duplicating code.  The timeout
in the outer loop is now restarted after every noise timeout, so it is
now possible for the total timeout to be infinite; previously, the maximum
total timeout was 150000 seconds.

85373d20b1 Implement an optional TIMEOUT value while entering the boot parameter
string.  This avoids indefinite hangs e.g. when used on a noisy serial
console.  It's not turned on by default.

0f72d204e6 Reset defaults in case of boot() is looping several times (e.g. the
user has entered a bogus kernel name in the first place).

Also fix the broken #ifdef FORCE_COMCONSOLE, it has been disabled by
accident.  (NB: the keyboard probe remains disabled however.)

Few cosmetic fixes (declare functions to be void instead of int),
while i've been at this.

Pointed out by: wosch@cs.tu-berlin.de (Wolfram Schneider), for the init bug

15c99149f8 Boot block cleanup.
o Fix the keyboard probe to properly wait for the ready bit before
sending a command to the keyboard controller.  This should avoid the
problems some people are experiencing where the boot blocks hang the
system during keyboard probe.  (It does solve it for me.)

o Fix a bug that effectively prevented the boot blocks from ever
passing control to the serial console.  [while(--retries) instead of
while(retries--)]

o Gratuitously reduced the keyboard probe timeout from 500 to 5
seconds. :)

o Introduced a new option ``FORCE_COMCONSOLE'' as a commented-out
example in the Makefile, to force the usage of a serial console
regardless of a keyboard being connected or not.

o Moved all external declarations to boot.h, declared all functions
there, and ANSIfied all function declarations/definitions.
(printf() remains bogus, however -- i'm too lazy to fix this.)
We're in the ninetees, dunno why we should still support compilers
from the 70's.

b5d89ca8ad Load the kernel symbol table in the boot loader and not at compile time.
(Boot with the -D flag if you want symbols.)

Make it easier to extend `struct bootinfo' without losing either forwards
or backwards compatibility.

ddb_aout.c:
Get the symbol table from wherever the loader put it.
Nuke db_symtab[SYMTAB_SPACE].

boot.c:
Enable loading of symbols.  Align them on a page boundary.  Add printfs
about the symbol table sizes.
Pass the memory sizes to the kernel.
Fix initialization of `unit' (it got moved out of the loop).
Fix adding the bss size (it got moved inside an ifdef).
Initialize serial port when RB_SERIAL is toggled on.
Fix comments.
Clean up formatting of recently added code.

io.c:
Clean up formatting of recently added code.

netboot/main.c, machdep.c, wd.c:
Change names of bootinfo fields.

LINT:
Nuke SYMTAB_SPACE.
Fix comment about DODUMP.

Makefile.i386:
Nuke use of dbsym.
Exclude gcc symbols from kernel unless compiling with -g.
Remove unused macro.
Fix comments and formatting.

genassym.c:
Generate defines for some new bootinfo fields.  Change names of old ones.

locore.s:
Copy only the valid part of the `struct bootinfo' passed by the loader.
Reserve space for symbol table, if any.

machdep.c:
Check the memory sizes passed by the loader, if any.  Don't use them yet.

bootinfo.h:
Add a size field so that we can resolve some mismatches between the loader
bootinfo and the kernel boot info.  The version number is not so good for
this because of historical botches and because it's harder to maintain.
Add memory size and symbol table fields.  Change the names of everything.

Hacks to save a few bytes:

asm.S, boot.c, boot2.S:
Replace `ouraddr' by `(BOOTSEG << 4)'.

boot.c:
Don't statically initialize `loadflags' to 0.  Disable the "REDUNDANT"
code that skips the BIOS variables.  Eliminate `total'.  Combine some
more printfs.

boot.h, disk.c, io.c, table.c:
Move all statically initialzed data to table.c.

io.c:
Don't put the A20 gate bits in a variable.

f778c9da00 Submitted by: Bill Paul (wpaul@ctr.columbia.edu)
Obtained from:
bios boot block changed to allow booting from both the attached graphics
display and from a serial port. (A specially compiled serial boot block
is no longer necessary.) The boot block should detect the presence or
absence of a keyboard: if there is no keyboard, COM1 is turned into the
console. This simulates the behavior of the Sun boot PROMs. Unplug your
keyboard, attach a terminal to COM1 and you should be ready to go. :)

3dea9c24ac Improved the user interface:
1) Added file list capability via '?'.
2) Arranged usage info to be more unix-like.
3) Fixed backspace over prompt annoyance.

dfc5d1d4eb Makefile: add ${LDDESTDIR} to linking of boot code so ${DESTDIR}/usr/lib
is used instead of /usr/lib

io.c: add #include <machine/cpufunc.h> as instructed by David Greenman to
avoid inb/outb linking errors.
NOTE:  I just discovered that if GNUC is not used the inline functions will not be expanded from the include file and real inb/outb functions would
be needed.

df9ab3049d Removed inclusion of pio.h and cpufunc.h (cpufunc.h is included from
systm.h). Merged functionality of pio.h into cpufunc.h. Cleaned up some
related code.

3f9e73d24f Changed delay mechanism to rely more on I/O spinning. If spinning on the
like this is bad news, it will have to be revised.
Shortened some verbose messages for when the kernel is loaded below 640k.
Updated version number.
