70562420ce Support multiple files on the command line (they're catted together).
Ditch a.out support while we're here (to save updating it).

98253a5467 It seems that all versions of BBC BASIC V can load a text file specified on
the command line, so we don't need to tokenize it first.

This makes it less than clear what file type BBBB should have, so let's not
make an issue of it.

564a044dcb Using bsd.man.mk looked silly without a man page. Use bsd.prog.mk without

c62d17a551 rationalize the use of b_flags for geteblk() buffers.
rather than assigning to the whole field, set or clear individual flags,
which implies that the B_BUSY and B_INVAL flags will remain set.
this allows us to make the assertion in brelse() that B_BUSY is set,
which is the purpose of all this.

a449e4af6d Ensure that the IOC is attached before any other devices, mostly because
the UPC driver needs to know whether the system's got an IOEB in it.

The way this is implemented is a mess -- I need to get my mind round
autoconfiguration again.

7270db5ec0 Change to semantics of irq_establish: IRQs are now enabled by default, which
I think is the same as all other ports.

9e47af8814 enable rnd device. they are now mandatory for ssh/sshd support,
so it makes more sense to enable it.
please disable them if there's any issues, but in that case, in-tree
ssh/sshd won't work.

49c105ffdb add new macro BOOT_FLAG() (defined in <sys/boot_flag.h>) - this
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.

b6ba812d35 Much juggling of pmap startup sequence:
* All of pmap_init is now deferred to the first call of pmap_create.  This
  allows us to allocate stuff dynamically using malloc.
* pv_table (which is needed before malloc is available) is temporarily
  allocated using pmap_steal_memory in pmap_bootstrap, and then
  re-allocated using malloc in pmap_create, with the old allocation being
  given back to UVM.  This should save some memory on small machines, but
  the malloc overhead probably soaks it up.

3112fd4f14 Add a pmap_steal_memory implementation. This has two good consequences.
First, it reduces the kernel text segment by 1k or so.
Second, it should enable me to eventually allocate the pv_table dynamically.

f3ef35c447 Add rudimentary 80C04 support (basically saying "Oh look, an 80C04!").
Move printing the initial ":" into the board driver, like i82586.c does.
Don't bother printing the amount of RAM, as it's always 64 KB.

40aba7cd4d Split the arm26 Ether3 (ea) driver into an MI driver for the SEEQ 8005 chip,
and a front-end driver for the Ether3.  Only semantic change is to remove
ea_claimirq() and ea_releaseirq() on the grounds that the seem too spurious
to warrant a callback to the front-end.

35dc9595d6 Move the user structure for process 0 into the same page as its stack segment,
the same as for every other process.  It probably doesn't matter, but it makes
me feel more comfortable.

72a24b4eae Add an align argument to uvm_map() and some callers of that
routine.  Works similarly fto pmap_prefer(), but allows callers
to specify a minimum power-of-two alignment of the region.
How we ever got along without this for so long is beyond me.

4db6fc7542 Make need_resched() take a "struct cpu_info *" argument. This
causes gives a primitive form of processor affinity.  Its use in
roundrobin() still needs some work.

a86d1f4891 Add a lock around the scheduler, and use it as necessary, including
in the non-MULTIPROCESSOR case (LOCKDEBUG requires it).  Scheduler
lock is held upon entry to mi_switch() and cpu_switch(), and
cpu_switch() releases the lock before returning.

Largely from Bill Sommerfeld, with some minor bug fixes and
machine-dependent code hacking from me.

d7eebd9227 Basic driver for CHIPS 82C710 Universal Peripheral Controller and friends,
as used on later arm26 system (A5000, A4, A3010, A3020, A4000).

What we have got:
...
upc0 at iobus0 base 0x010000: config state bb 87 1c 00 00
fdc at upc0 offset 0x3f4 not configured
wdc0 at upc0 offset 0x1f0
lpt0 at upc0 offset 0x278
com0 at upc0 offset 0x3f8: ns8250 or ns16450, no fifo
...

What we haven't got:
 - FDC support (found, but not configured).
 - Clearing lpt interrupts on arm26 systems (needs help from IOEB).
 - A upc(4) manual page.
 - More than minimal testing (my A3020s don't have root devices).
 - A proper probe routine (arm26 can't use one anyway).

85dda25e94 move "options PULLDOWN_TEST" into sys/sys/mbuf.h (in #ifdef _KERNEL),
as it is no wthe default setting for everyone.

the reason we still use the name "PULLDOWN_TEST" while it is now default:
kame code sharing.
