89200512b3 Fix warnings.
nxge: cast page size fragments down to (int). If the vm's demand paging
PAGE_SIZE is ever too big for that, we've got far bigger problems.
ofw: move va_start() a little earlier. gcc-4.2 doesn't like us modifying
the last arg before the va_start().

bba6f0a901 - Add a new method ofw_bus_default_get_devinfo() that allows to retrieve
a newly introduced struct ofw_bus_devinfo which can hold the OFW info
  of a device recallable via the ofw_bus KOBJ interface. Introduce a set
  of functions ofw_bus_gen_get_*() which use ofw_bus_default_get_devinfo()
  to provide generic subroutines for implementing the rest of the ofw_bus
  KOBJ interface in a bus driver.
  This is inspired by bus_get_resource_list() and bus_generic_rl_*_resource()
  and allows to reduce code duplication in bus drivers as they only have
  to provide an ofw_bus_default_get_devinfo() implementation in order to
  provide the ofw_bus KOBJ interface via ofw_bus_gen_get_*().
- While here add a comment to ofw_bus_if.m describing the intention of
  the ofw_bus KOBJ interface.

a3624af7d8 The mediasize shouldn't be multipled by the sector size when it was
in bytes to start off with. This caused the GPT geom sniffer to attempt
a seek just back from the end of the 'disk', which resulted in a > 4G
seek, causing gdb psim to exit since it only supports 32-bit seeks.

The size of the disk should really be specified in the psim device tree,
but for now do the minimal amount of work to get psim to run again.

95bc568977 Add new function ttyinitmode() which sets our systemwide default
modes on a tty structure.

Both the ".init" and the current settings are initialized allowing
the function to be used both at attach and open time.

The function takes an argument to decide if echoing should be enabled.
Echoing should not be enabled for regular physical serial ports
unless they are consoles, in which case they should be configured
by ttyconsolemode() instead.

Use the new function throughout.

26280d88d7 - Introduce an ofw_bus kobj-interface for retrieving the OFW node and a
subset ("compatible", "device_type", "model" and "name") of the standard
  properties in drivers for devices on Open Firmware supported busses. The
  standard properties "reg", "interrupts" und "address" are not covered by
  this interface because they are only of interest in the respective bridge
  code. There's a remaining standard property "status" which is unclear how
  to support properly but which also isn't used in FreeBSD at present.
  This ofw_bus kobj-interface allows to replace the various (ebus_get_node(),
  ofw_pci_get_node(), etc.) and partially inconsistent (central_get_type()
  vs. sbus_get_device_type(), etc.) existing IVAR ones with a common one.
  This in turn allows to simplify and remove code-duplication in drivers for
  devices that can hang off of more than one OFW supported bus.
- Convert the sparc64 Central, EBus, FHC, PCI and SBus bus drivers and the
  drivers for their children to use the ofw_bus kobj-interface. The IVAR-
  interfaces of the Central, EBus and FHC are entirely replaced by this. The
  PCI bus driver used its own kobj-interface and now also uses the ofw_bus
  one. The IVARs special to the SBus, e.g. for retrieving the burst size,
  remain.
  Beware: this causes an ABI-breakage for modules of drivers which used the
  IVAR-interfaces, i.e. esp(4), hme(4), isp(4) and uart(4), which need to be
  recompiled.
  The style-inconsistencies introduced in some of the bus drivers will be
  fixed by tmm@ in a generic clean-up of the respective drivers later (he
  requested to add the changes in the "new" style).
- Convert the powerpc MacIO bus driver and the drivers for its children to
  use the ofw_bus kobj-interface. This invloves removing the IVARs related
  to the "reg" property which were unused and a leftover from the NetBSD
  origini of the code. There's no ABI-breakage caused by this because none
  of these driver are currently built as modules.
  There are other powerpc bus drivers which can be converted to the ofw_bus
  kobj-interface, e.g. the PCI bus driver, which should be done together
  with converting powerpc to use the OFW PCI code from sparc64.
- Make the SBus and FHC front-end of zs(4) and the sparc64 eeprom(4) take
  advantage of the ofw_bus kobj-interface and simplify them a bit.

a82b25f9b2 Better OFW console support on Sun Ultra2 machines.
Ultra2 users may want to set OFWCONS_POLL_HZ to a value of '20'.
I have left default value at '4' as higher values can consume a more
than is acceptable amount of CPU, and we don't have a consensus yet
what is an optimal value.

073e8552f8 - Move OFW_NAME_MAX, used as a limit for OFW property names and device
identifiers, to openfirmio.h as OFIOCMAXNAME, so programs can use it
  for buffer sizes etc.
  Note: Although this is only a rough upper limit to make the code more
  robust and to prevent the allocation of ridiculous amounts of memory,
  the current limit of one page (8191 + '\0' in openfirm_getstr()) still
  appears a bit high. The maximum length of OFW property names is 31.
  I didn't find a maximum length for the device identifiers in the OFW
  documentation but it certainly is much smaller than 8191, too.
- Enable the OFIOCSET ioctl, i.e. move it out from under #if 0.
- Don't use openfirm_getstr() for the property value in OFIOCSET, there
  are also properties whose values aren't strings and it makes sense to
  use a different maximum length for property values than OFW_NAME_MAX/
  OFIOCMAXNAME. The maximum accepted property value is defined in
  openfirmio.h as OFIOCMAXVALUE (currently the maximum size of the value
  of the nvramrc property).
- Make OFIOCSET not return EINVAL when OF_setprop() returns a different
  length for the written value than it was told to write, this is normal
  for the text string values of the properties in the OFW /options node.
  Instead, only return EINVAL if OF_setprop() returned -1 (value could
  not be written or property could not be created). Add a comment about
  the specialty of the OFW /options node.
- Make OFIOCSET return the length of the written value returned by
  OF_setprop(), just like OF_getprop() does. Quite useful, at least for
  debugging.

0b7ed341e1 Change the disk(9) API in order to make device removal more robust.
Previously the "struct disk" were owned by the device driver and this
gave us problems when the device disappared and the users of that device
were not immediately disappearing.

Now the struct disk is allocate with a new call, disk_alloc() and owned
by geom_disk and just abandonned by the device driver when disk_create()
is called.

Unfortunately, this results in a ton of "s/\./->/" changes to device
drivers.

Since I'm doing the sweep anyway, a couple of other API improvements
have been carried out at the same time:

The Giant awareness flag has been flipped from DISKFLAG_NOGIANT to
DISKFLAG_NEEDSGIANT

A version number have been added to disk_create() so that we can detect,
report and ignore binary drivers with old ABI in the future.

Manual page update to follow shortly.

Change the defaults to be nullopen() and nullclose() which simply
