Fix various typos in comments, log messages and documentation.

Largely unify the <machine/cpu.h> headers on the m68k platforms.

Guard references to protorp with M68030.

Statically-initialize the '851 / '030 protorp with MMU51_SRP_BITS.  In
pmap_init(), re-initialize protorp with MMU51_CRP_BITS.  Remove the now-
redundant code that does this in each of the m68k platforms.

Stop using magic numbers for the MMU root pointer attributes and the
Translation Control register, and also get rid of "#if PGSHIFT == ..."
where those magic numbers are used.

Instead, define new macros: MMU51_SRP_BITS, MMU51_CRP_BITS, MMU51_TCR_BITS,
and MMU40_TCR_BITS, in terms of the definitions in mmu_{40,51}.h.  These
automagically adapt to 8K and 4K pages based on the machine-specific value
of PGSHIFT.

Allocalte enough reserved ST-RAM to make the old Xserver work by default.

Instead, check ST-RAM size and TT-RAM size on startup and restrict
size of reserved ST memory on lower RAM machines.

Closes PR port-atari/41002 from David Ross.

While here, make options ST_POOL_SIZE defparam'ed to make sure to

Move the iomem extent stuff managed by bus_space(9) and make them static.

Inspired by MD bus_space(9) implemantation of arc.
Briefly tested on TT030.

Fix I/O access failures for regions allocated by bus_space_map(9) on Milan.

Passing to PMAP_WIRED against I/O spaces seems problematic,
probably after yamt-km branch merge, which was committed
between NetBSD 3.0 and NetBSD 4.0.
(i.e. ISA and PCI devices on Milan didn't work after 4.0 release)

XXX:
According to pmap(9) man page, the "flags" arg for pmap_enter(9)
doesn't take VM_PROT_READ and VM_PROT_WRITE, but pmap_enter()
implementation in sys/arch/m68k/m68k/pmap_motolora.c historically
checks them.

Fix silent hang during config_console() (before consinit()) on Milan.
config_console() was a dirty hack used by ancient m68k ports
to probe and initialize console devices before "real" configure(9),
using subset of configure(9) functions.

In that case, most device specific data (except I/O access method)
are not initialized so we must not access device specific device_t and
softc structures in config_console() cases.

Fix silent hang after isa_intr_establish() on Milan.
The problems (wrong macro replacements) were slipped in rev 1.107:
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/atari/atari/locore.s#rev1.107
Handle yet another atari specific quirk in the MI ISA fdc(4)/fd(4) driver.
This makes fd(4) drive(s) (which is necessary for installation)
properly attached on Milan.
atari uses "fdcisa" and "fdisa" for ISA fdc to co-exist other fd(4)
drivers, on-board (atari/dev/fd.c) one and Hades (atari/dev/hdfd.c) one.

Use a proper PSL value to be passed to splx(9) functions.
This should have been changed on yamt-splraiseipl branch merge
back in 2006, which made MI IPL_xxx values independent from
m68k MD PSL values for the %sr register.

Restore piixide(4) for Milan and disable other pciide devices.
piixide was removed in rev 1.18 and the log message said
"because Intel IDE disk controllers only exist as part of
 Intel chipsets for x86 systems" but the Milan actually has
the Intel 82371FB southbridge on its board.
Other pciide devices are unlikely necessary for the default
kernel for such a rare machine.
Also fix pasto in comment.

Skip NVRAM checksum check and re-initialization on Milan.
Milan's firmware seems to use different check method.

Ack EOI for IRQ_SLAVE of the master PIC after ack for IRQ of the slave PIC.
I'm not sure if there are possible races in the original code, but
this is what i8259_asm_ack2() in sys/arch/x86/include/i8259.h does
and it looks this change makes a Milan kernel a bit stable.
Replace CRTC register values with ones taken from sys/dev/ic/vga_subr.c.
This fixes noise around column 3 and 4 and makes screen output clearer
on Milan with S3 Trio64V.

Explicitly setup the secondary IDE interrupt of PIIX on Milan.
The secondary IDE interrupt is connected to MBIRQ0 on PIIX, but
the Milan's ROM bootloader (at least version 0.99.7) doesn't seem
to setup the MBIRQ0 register to route it to IRQ15.

On Milan, also explicitly disable MBIRQ1 on PIIX.
Milan's ROM bootloader v1.2 and v1.4 incorrectly set MBIRQ0 connected
to the secondary IDE to IRQ14 (not 15) and unused MBIRQ1 to IRQ15,
so both IDE channels don't work properly.

Add dumb memory probe routines for Milan to use all available memory.
Tested on Milan with 32Mx1, 32Mx4, 128MBx1, and 128MBx3.
(bootloader ROM fails to load TOS with 128MBx4)
No particular comment on port-atari@:
 http://mail-index.netbsd.org/port-atari/2018/02/09/msg000580.html

Provide wdboot as a copy of sdboot for Milan.
It looks Milan's bootloader ROM emulates IDE disks as SCSI disks
so sdboot works for them, but atari's installboot checks a specified
device name and requires wdboot for wd(4) devices.

Fix another possible out of bounds.

Replace bus_dmamap_sync(9) op with a newer one taken from m68k/bus_dma.c.
This could fix memory corruption issue caused by PREREAD ops with regions
whose boundaries are not aligned at cacheline size.

Add dumb memory probe routines for Milan to use all available memory.

Use actual physmem size for allocation of bootstrap extra PT pages
to avoid wasting pages on low memory machines.
Improves atari specific part of PR/45915, tested on TT030.
Reserve more bootstrap kernel PT pages if options EXTENDED_MEMORY is defined
for VA allocation in the extended memory probe function and possible 128MB
memory on 060turbo, as worksaround for x68k specific part of PR/45915.
Fixes GENERIC kernel panic on X68030 even without extended memory.
XXX: we should rather have proper probe function before pmap_bootstrap()
Tested on 060turbo with 128MB SIMM by Y.Sugahara, and also
tested on XM6i with 68030 and custom 128MB memory settings by isaki@.

Use actual physmem size for allocation of bootstrap extra PT pages

Improves atari specific part of PR/45915, tested on TT030.

merge to -current.

The recent kmem changes allocate a large kernel address space before
pmap_init() is called, and the initial kernel PT pages aren't enough
for the allocations pmap_init().  This fails because pmap_kenter_pa()
tries to allocate a new kernel PT page and traps because the pmap has
not been initialized.  When computing the number if initial kernel PT
pages, include enough to allow kmem to map the physical memory.  This
should fix PR/45915.  OK by releng@.  One mac68k system has been verified
to boot.  Volunteers to test the others welcome.  Amigas with at least
up to 128MB of memory were OK, but larger memory will need some adjusting.

Use appropriate macro during pmap initialization:
- use SYSMAP_VA, SEGSHIFT for Sysmap address and table entries
- use TIA_SIZE, TIB_SIZE for sizes of table entries

Now page size dependent numbers are almost replaced with proper macro.

Tested on atari, hp300, and news68k.

Move initialization of protection_codes[] and kernel_pmap()
from MD pmap bootstrap sources to common pmap_bootstrap_finalize().

Tested on atari, hp300, mac68k, and news68k.

XXX: Why is protection_codes[] array initialized at run time?

pm_stfree in struct pmap is a bitmap value so make it unsigned.

Use common pmap_bootstrap_finalize() to initialize lwp0 uarea etc.
Tested on TT030.

- Use uvm_lwp_setuarea() instead of directly setting address to lwp_t::l_addr.
- Replace most remaining uses of l_addr with uvm_lwp_getuarea() or lwp_getpcb().
- Amend assembly in ports where it accesses PCB via struct user.
- Rename L_ADDR to L_PCB in few places.  Reduce sys/user.h inclusions.

Kill proc0paddr.  Use lwp0.l_addr instead.

Remove duplicate #includes, patch contributed in private mail
by Slava Semushin <slava.semushin@gmail.com>.

To verify that no nasty side effects of duplicate includes (or their
removal) have an effect here, I've compiled an i386/ALL kernel with

files was in shifted line numbers in some assert() calls.
The comparison of the .o files was based on the output of "objdump -D".

so that it is always safe to reference curproc (*de*referencing curproc
is another story, but that's always been true).

MD Scheduler Activation bits for Atari.
Compile-tested only.

Catch up to -current.

file atari_init.c was added on branch nathanw_sa on 2001-11-17 23:18:02 +0000

PCI_VGA_SIZE -> PCI_MEM_SIZE. (Plus some comments on those constants).

Adapt for the Milan.

Sync with HEAD.

Prepare assembly parts for an eventual transition to ELF. Mostly from a
diff from Steve Woodford.

No longer update the PAGE_* variables. They have turned into compile time
constants.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Pullup: atari_init.c 1.49-1.50, pmap.c 1.56-1.57. Approved by thorpej.

Get 060 CacheCopyBack support in line with the amiga (and working ;-)

remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>

Get 060 CacheCopyBack support in line with the amiga (and working ;-)

remove redudant <vm/pmap.h> includes. <vm/pmap.h> -> <uvm/uvm_pmap.h>

Centralise the declarations of cpu_model, machine, machine_arch,
osrelease, and ostype and remove "extern char foo[];" (for hostname
and domainname too).

Also delete redunctant decl of boottime in kern_info_43.c.

Add bootm_init() prototype.

Pull up to last week's -current.

Implement an allocator for VA-space using fixed extent maps. It is now
possible to allocate VA-space before uvm is initialized.

Allocate the physical RAM from the extent map.

Sync with -current

Use extent maps.

Reverse the order in which PCI cards are scanned. Now the order matches the
TOS-scan order. This causes TOS & NetBSD to use the same video card on
a system with multiple VGA cards.

Changed grf mmap that it is closer to XFree. VGA memory on et4000/et6000
is now at offset 0xa0000.

Make it compile with -DDEBUG again.

Get rid of vm_offset_t/vm_size_t

defopt DDB.

Back out the defopt for M680?0. As pointed out to me, this breaks ports which
dont use the M680?0 the way Amiga, Atari, Mac68k, and X68k do. I must have
missed this in the past discussion about this project.

Move M680[2346]0 to opt_m68kcpu.h.
XXX Some explicit dependencies could be removed now from the individual
arch/$ARCH/conf/Makefile.$ARCH files, but this is still to be done.

Only try to initialize the PCI-bus when NPCI > 0.

Update Hades PCI support:
  - Initialize the PCI bus and hand-out mem and i/o addresses. (there is
    still lots of room for improvements here...)
  - Implement the interupt functions

Pull rev 1.34 up from trunk

Do not relocate the kernel to TT-Ram by default. Some TT's choke on this. You
can now opt for relocation by either setting the RELOC_KERNEL config option
or patching 'reloc_kernel' to something other than zero.

Update marc-pcmcia branch from trunk.

Use a buserror handler that just tests for 'nofault' being set when the
MMU is not yet initialized. This behaviour is necessary when probing
for the machine type - because we need the type before we can setup the
tables....

Pull in latest Amiga bus/address error handling.

s/atari_round_page/m68k_round_page/

* finalize 060 stuff.

For locore.s also nuke cacheop-functions now provided in m68k.

Adjust for new <m68k/kcore.h>

Merge in Changes from The Trunk.

Push out some 060 support. It's all untested and mostly copied in from the
amiga-port.

Enable SCC & MFP interrupts through the vme_mask register instead of
using the sys_mask register.

update from trunk

Add a 'size' argument to badbaddr(). This is very useful on busses that
only accept certain size accesses on a specific address range. Like the
VME bus.

Fix the machine-type detection, the Falcon was detected as a Hades. Regroup
the hardware initialisations in a separate function and make sure
that the Midi-ACIA is properly initialized. This prevents MIDI traffic
to lockup the keyboard.

Oops, the declaration of cputype was gone...

Get rid of 'cpu040' variable. Use 'mmutype' or 'cputype' for testing
instead.

Add intr_establish/disestablish functions. Currently only the lpt-driver
is converted to use them...

Initialisation of proc0->p_addr. (Gordon Ross)
This, in conjunction with the trap.c changes, solve the crashes when
referencing illegal addresses in the debugger. Thanks Jason for providing
the trigger and solution ;-)

backout previous kprintf changes

printf -> kprintf, sprintf -> ksprintf

Initialize MFP2 on both TT&HADES.

- Make it compile & work for the 68040
- Map the various I/O areas just below Sysmap
- Cleanup a bit
- Fix machine-type detection to recognize the Hades.

Checkpoint integration of 68040 MMU support. Also fix oversight in allocation
of (virtual) I/O area address range.

- Cleanup a bit
- Remove mapping of page zero
- Remove hackery around the first 8 bytes that were mapped to ROM by hardware

Corrections for removed <sys/cpu.h> and some more prototypes.

Yet more prototyping and -Wall fixes.

Prototyping.

Take out direct access to the YM2149. The chip definitions are moved
from video.h to ym2149reg.h.

Add the include files and the atari kernel support for new format panic
dumps.

Make an NMI activate the debugger. This only works on a TT and needs a small
hardware patch. This makes it easier to debug drivers that hang on an ipl
> splsoft.

Initialize the YM sound-chip to a sane state.

Support & require MACHINE_NONCONTIG

Make ST_POOL_SIZE configurable through config.

Remove double mapping of stack.

Added machine type detection, the presence of the 2nd MFP determines
if the machine is a Falcon or a TT030. The type is added to 'machineid'.
Interrupt  initialisation is now dependend on the machine type.

Report "real mem" correctly and make one single module for handling
software interrupts.

- Remove cpuspeed
- Remove dead code  (stmem_steal())
- Use round_page() on st_pool_size before using. This prevents crashes
  when it is 'binpatched' with a value that is not a multiple of the
  page size.
