controllers of Sun PCIO-2 chips which are used onboard in most of
the newer PCI-based sun4u machines (cosmetic change as they were also
already probed as generic FWOHCI without this). As with gem(4), hme(4)
and ohci(4) detect whether their intpin register is valid and correct
it if necessary, i.e. set the respective IVAR to the right value for
allocating the IRQ resource, as some of them come up having it set
to 0 (in fact in all machines I'm currently aware of the FireWire
part being enabled). This fixes attaching affected controllers.

We can't call KeFlushQueuedDpcs() during bootstrap (cold == 1), since
the flush operation sleeps to wait for completion, and we can't sleep
here (clowns will eat us).
On an i386 SMP system, if we're loaded/probed/attached during bootstrap,
smp_rendezvous() won't run us anywhere except CPU 0 (since the other CPUs
aren't launched until later), which means we won't be able to set up
the GDTs anywhere except CPU 0. To deal with this case, ctxsw_utow()
now checks to see if the TID for the current processor has been properly
initialized and sets up the GTD for the current CPU if not.
Lastly, in if_ndis.c:ndis_shutdown(), do an ndis_stop() to insure we
really halt the NIC and stop interrupts from happening.
Note that loading a driver during bootstrap is, unfortunately, kind of
a hit or miss sort of proposition. In Windows, the expectation is that
by the time a given driver's MiniportInitialize() method is called,
the system is already in 'multiuser' state, i.e. it's up and running
enough to support all the stuff specified in the NDIS API, which includes
the underlying OS-supplied facilities it implicitly depends on, such as
having all CPUs running, having the DPC queues initialized, WorkItem
threads running, etc. But in UNIX, a lot of that stuff won't work during
bootstrap. This causes a problem since we need to call MiniportInitialize()
at least once during ndis_attach() in order to find out what kind of NIC
we have and learn its station address.
What this means is that some cards just plain won't work right if
you try to pre-load the driver along with the kernel: they'll only be
probed/attach correctly if the driver is kldloaded _after_ the system
has reached multiuser. I can't really think of a way around this that
would still preserve the ability to use an NDIS device for diskless
booting.
bzip2 support provided, and amd64 depended on. Amd64 has a custom
${.OBJDIR}/machine symlink in it and the -I. picked this up. Without
it, the libstand code was being compiled in 32 bit mode, but with 64 bit
machine headers.
prevent anything from making calls to the NIC while it's being shut down.
This is yet another attempt to stop things like mdnsd from trying to
poke at the card while it's not properly initialized and panicking
the system.
Also, remove unneeded debug message from if_ndis.c.
user to interrupt autoboot process at all. Currently, even when
`autoboot_delay' is set to 0, loader(8) still allows autoboot process to be
interrupted by pressing any key on the console when the loader reads kernel
and modules from the disk. In some cases (i.e. untrusted environment) such
behaviour is highly indesirable and user should not be allowed to interfere
with the autoboot process at all.

correct it if necessary, i.e. set the respective IVAR to the right
value for allocating the IRQ resource, as some of them come up
having it set to 0 (mainly those used in Blade 100 and the first
one on AX1105 boards). This fixes attaching affected controllers.
Correcting the intpin value might be better off in the PCI code
via a quirk table but on the other hand gem(4) and hem(4) also
correct it themselves and at least for the USB controller part
the intpin register is truely hardwired to 0 and can't be changed.
This means that we would have to hook up the quirk information
in a lot of places in the PCI code (i.e. whenever the value of the
intpin register is read from or written to the pci_devinfo of the
respective device) in order to do it the right way.

- Add locking.
- Account for if the MC146818_NO_CENT_ADJUST flag is set we don't need
to check wheter year < POSIX_BASE_YEAR.
- Add some comments about mapping the day of week from the range the
generic clock code uses to the range the chip uses and which I meant
to add in the initial version.
- Minor clean-up, use __func__ instead of hardcoded function names in
error strings.
o in the rtc(4) front-end additionally:
- Don't leak resources in case mc146818_attach() fails.
- Account for ebus(4) defaulting to SYS_RES_MEMORY for the memory
resources since ebus.c rev. 1.22.
- Add support for storing the century in MK48TXX_WDAY_CB on MK48Txx with
extended registers when the MK48TXX_NO_CENT_ADJUST flag is set (and which
is termed somewhat confusing as it actually means don't manually adjust
the century in the driver).
- Add the MI part of interfacing the watchdog functionality of MK48Txx with
extended registers with watchdog(9). This is inspired by the SunOS/Solaris
drivers for the 'eeprom' devices also having watchdog support. I actually
expected this to work out of the box on Sun Exx00 machines with 'eeprom'
devices which have a 'watchdog-enable' property. On terminal count of the
the watchdog timer however only the MK48TXX_FLAGS_WDF bit rises but the
reset signal and the interrupt respectively (depending on whether the
MK48TXX_WDOG_WDS bit of the chip and the MK48TXX_WDOG_ENABLE_WDS flag
of the driver respectively is set) goes nowhere. Apparently passing the
reset signal on to the WDR line of the CPUs has to be enabled somewhere
else but we don't have documentation for the Exx00 specific controllers.
I decided to commit this nevertheless so it can be enabled in the eeprom(4)
front-end later in e.g. 6.0-STABLE without breaking the API. Besides the
Exx00 the watchdog part of the MK48Txx should also work on E250 and E450.
Possibly also without extra fiddling on these machines but I haven't
found someone willing to give it a try on such a machine so far.

eeprom_ebus_attach() and eeprom_sbus_attach() into eeprom_attach()
respectively. Since the introduction of the ofw_bus interface some
time ago and now that ebus(4) also uses SYS_RES_MEMORY for the

compatibility with ISA devices while in fact all known EBus devices
actually use memory space turned out to be not a good idea as so far
there is only the 'rtc' device known to show up either on an EBus or
ISA bus but not on any of the other busses used on sparc64. However
there are quite a couple of them that show up on either EBus, FireHose
or SBus. In order to save extra code in the respective drivers switch
ebus(4) to actually use SYS_RES_MEMORY for the memory resources of
its children. At least for transition still accept SYS_RES_IOPORT
and silently change it to SYS_RES_MEMORY. [1]
- In ebus_probe() use ofw_bus_get_name() instead of re-implementing it
via ofw_bus_get_node() and OF_getprop().
- Remove some unused variables.
- Use FBSDID.
Discussed with: tmm (some time ago)
the iteration variable as the RID when adding the respective resource
to the child via bus_set_resource(). In case a device has both I/O
and memory resources this generates gaps in the newbus resources of
the child, e.g. its first memory resource might end up as RID 1.
To solve this mimic resource_list_add_next() via resource_list_find()
and bus_set_resource(); we can't just use resource_list_add_next()
here as this would circumvent the limit checks in isa_set_resource()
of the common ISA code.
This however is more or less a theoretical problem so far as all known
ISA devices on sparc64 soley use I/O space.
- Just use bus_generic_rl_release_resource() for isa_release_resource()
instead of re-implementing the former.
- Improve some comments to better reflect reality, minor clean-up and
simplifications, return NULL instead of 0 were appropriate.
