0bd051b869 Unbreak SBus cards which have been broken (apparently) for a while.
Most of the pieces came from Marius- correct settings for channels
and resource management. The one piece missing was that you cannot
for SBus cards replace 32 bit operations with A64 operations- not
supported.

2df76c160b Add 8Gb support (isp_2500). Fix a fair number of configuration and
firmware loading bugs.

Target mode support has received some serious attention to make it
more usable and stable.

Some backward compatible additions to CAM have been made that make
target mode async events easier to deal with have also been put
into place.

Further refinement and better support for NP-IV (N-port Virtualization)
is now in place.

Code for release prior to RELENG_7 has been stripped away for code clarity.

9a1b0d43c2 Temporarily desupport simultaneous target and initiator mode.
When the linux port changes were imported which split the
target command list to be separate from the initiator command
list and the handle format changed to encode a type in the handle
the implications to the function isp_handle_index (which only
the NetBSD/OpenBSD/FreeBSD ports use) were overlooked.

The fault is twofold: first, the index into the DMA maps
in  isp_pci is wrong because a target command handle with
the type bit left in place caused a bad index (and panic)
into dma map. Secondly, the assumption of the array
of DMA maps in either PCS or SBUS attachment structures is
that there is a linear mapping between handle index and
DMA map index. This can no longer be true if there are
overlapping index spaces for initiator mode and target
mode commands.

These changes bandaid around the problem by forcing us
to not have simultaneous dual roles and doing the appropriate
masking to make sure things are indexed correctly. A longer
term fix is being devloped.

3cce220cba Remove dependency on ispfw and firmware as modules.
Either they're there early and the ispfw sets have
registered themselves, or they're not.

The module dependency stuff isn't quite what we want
anyway. If the user doesn't want the load placed on
system memory by loading the firmware, they don't
specify it to be loaded (either by being linked in
or via being a module to be loaded and then hooked
in with firmware(9)). It doesn't then make sense to
then override what they want by pulling it in anyway.

This might be able to work if we were able to pull in
just exactly what we needed for the card we have- but
that's an optimization left for the future.

9a5af41076 Convert isp(4) and ispfw(4) to use firmware(9) to manage firmware
loading for the QLogic cards.

Because isp(4) exists before the root is mounted, it's not really
possible for us to use the kernel's linker to load modules directly
from disk- that's really too bad.

However, the this is still a net win in in that the firmware has
been split up on a per chip (and in some cases, functionality)
basis, so the amount of stuff loaded *can* be substantially less
than the 1.5MB of firmware images that ispfw now manages. That is,
each specific f/w set is now also built as a module. For example,
QLogic 2322 f/w is built as isp_2322.ko and Initiator/Target 1080
firmware is built as isp_1080_it.ko.

For compatibility purposes (i.e., to perturb folks the least), we
also still build all of the firmware as one ispfw.ko module.

This allows us to let 'ispfw_LOAD' keep on working in existing
loader.conf files. If you now want to strip this down to just
the firmware for your h/w, you can then change loader.conf to
load the f/w you specifically want.

We also still allow for ispfw to be statically built (e.g., for
PAE and sparc64).

Future changes will look at f/w unloading and also role switching
that then uses the kernel linker to load different ips f/w sets.

1dae40eb49 a) clean up some declaration stuff (i.e., make more modern with respect
to getting rid u_int for uint and so on).

b) Turn back on 64 bit DAC support. Cheeze it a bit in that we have two
DMA callback functions- one when we have bus_addr_t > 4 bits in width and
the other which should be normal. Even Cheezier in that we turn off setting
up DMA maps to be BUS_SPACE_MAXADDR if we're in ISP_TARGET_MODE. More work
on this in a week or so.

c) Tested under amd64 and 1MB DFLTPHYS, sparc64, i386 (PAE, but insufficient
memory to really test > 4GB). LINT check under amd64.

8d727356c6 - Don't shift the clock frequency in MHz left by 8 before assigning it
to sbus_mdvec.dv_clock as sbus_mdvec.dv_clock is meant to be specified
  in MHz. While this was a bug it shouldn't have affected FreeBSD/sparc64
  as sbus_mdvec.dv_clock is used to limit the clock rate of chips when
  a machine isn't able to support them at maximum speed which isn't the
  case for sun4u machines.
- Remove the code that checks whether the clock frequency returned by
  sbus_get_clockfreq() is 0 and falls back to 25MHz if it is as that's
  already done in sbus(4).

e526523707 First of several commits as this driver is dusted off and maybe brought
up to date.  Principle changes for this reelase is to support 2K Port Login
firmware. This allows us to support the 2322 (and 2422 4Gb) cards which only
come with the 2K Port Login firmware. The 2322 should now work- but we don't
have firmware sets for it in ispfw (as the change to load 2K Port Login f/w
hasn't been made- that f/w is so big it has to be loaded in more than one
chunk).

Other changes are the beginnings of cleaning up some long standing target
mode issues. The next changes here will incorporate a lot of bug fixes
from others.

Finally, some copyright cleanup and attempts to make the parts of the
driver that are FreeBSD specific start conforming more to FreeBSD style.

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.

f6b1c44d1f Mega busdma API commit.
Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg.
Lockfunc allows a driver to provide a function for managing its locking
semantics while using busdma.  At the moment, this is used for the
asynchronous busdma_swi and callback mechanism.  Two lockfunc implementations
are provided: busdma_lock_mutex() performs standard mutex operations on the
mutex that is specified from lockfuncarg.  dftl_lock() is a panic
implementation and is defaulted to when NULL, NULL are passed to
bus_dma_tag_create().  The only time that NULL, NULL should ever be used is
when the driver ensures that bus_dmamap_load() will not be deferred.
Drivers that do not provide their own locking can pass
busdma_lock_mutex,&Giant args in order to preserve the former behaviour.

sparc64 and powerpc do not provide real busdma_swi functions, so this is
largely a noop on those platforms.  The busdma_swi on is64 is not properly
locked yet, so warnings will be emitted on this platform when busdma
callback deferrals happen.

If anyone gets panics or warnings from dflt_lock() being called, please
let me know right away.
