b2f314b812 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.

d01394099a Push things closer to path failover by implementing loop down and
gone device timers and zombie state entries. There are tunables
that can be used to select a number of parameters.

loop_down_limit - how long to wait for loop to come back up before
declaring
all devices dead (default 300 seconds)

gone_device_time- how long to wait for a device that has appeared
to leave the loop or fabric to reappear (default 30 seconds)

Internal tunables include (which should be externalized):

quick_boot_time- how long to wait when booting for loop to come up

change_is_bad- whether or not to accept devices with the same
WWNN/WWPN that reappear at a different PortID as being the 'same'
device.

Keen students of some of the subtle issues here will ask how
one can keep devices from being re-accepted at all (the answer
is to set a gone_device_time to zero- that effectively would
be the same thing).

7e1db24f98 The first of 3 major steps to move the CAM layer forward to using
the CAM_NEW_TRAN_CODE that has been in the tree for some years now.

This first step consists solely of adding to or correcting
CAM_NEW_TRAN_CODE pieces in the kernel source tree such
that a both a GENERIC (at least on i386) and a LINT build
with CAM_NEW_TRAN_CODE as an option will compile correctly
and run (at least with some the h/w I have).

After a short settle time, the other pieces (making
CAM_NEW_TRAN_CODE the default and updating libcam
and camcontrol) will be brought in.

This will be an incompatible change in that the size of structures
related to XPT_PATH_INQ and XPT_{GET,SET}_TRAN_SETTINGS change
in both size and content. However, basic system operation and
basic system utilities work well enough with this change.

c25fb06d92 add a newbus method for obtaining the bus's bus_dma_tag_t... This is
required by arches like sparc64 (not yet implemented) and sun4v where there
are seperate IOMMU's for each PCI bus...  For all other arches, it will
end up returning NULL, which makes it a no-op...

Convert a few drivers (the ones we've been working w/ on sun4v) to the
new convection...  Eventually all drivers will need to replace the parent
tag of NULL, w/ bus_get_dma_tag(dev), though dev is usually different for
each driver, and will require hand inspection...

44c8c2fc91 Fix 2KLOGIN code to specify *ibits* (not *obits*) so that the
options field in register 10 will be deterministic, not random.

Correct the number of input bits for EXECUTE_FIRMWARE 0..1 to
0..2- the 2322 and 24XX cards use mailbox register 2 to specify
whether the f/w being executed is freshly loaded or not.

Correct the number of input bits for {READ,WRITE}_RAM_WORD_EXTENDED
so that register 8 gets picked up.

Fix the indexing and offset for the 2322 f/w download so that it
correctly puts the different code segments where they belong.

Move VERIFY_CHECKSUM to be the 'else' clause to 2322 f/w downloads-
the EXECUTE_FIRMWARE command for 2322 and 24XX cards will tell you
if the f/w checksum is incorrect and VERIFY_CHECKSUM only works for
RISC SRAM address < 64K so you can only do a VERIFY_CHECKSUM on the
first of the 3 f/w segments for the 2322.

Shorten the delay for the continuation mailbox commands- 1ms is
ridiculous (100us is more likely).

All of the more or less is really only for the 2322/6322 cards.

a6dea567ad 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.

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

ed93f993fd - 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).

2ad9b36fa1 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.

LDT" before coming up. When this gets a bit more testing, I'll fix the PAE
conf file to allow isp devices.

23928ffbb6 Until I can get a clearer architecture from PHK about why he wants
the geometry code to grab a mutex that prohibits any driver on the
stack below it from sleeping, it's not safe to allow anything in
the top half of isp to sleep (excepting the thread that Fibre Channel
instances use to re-scan loops/fabrics).

f8c9f3a5e2 - 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.

dfcfecd6e4 These are changes to allow to use the Intel C/C++ compiler (lang/icc)
to build the kernel. It doesn't affect the operation if gcc.

Most of the changes are just adding __INTEL_COMPILER to #ifdef's, as
icc v8 may define __GNUC__ some parts may look strange but are
necessary.

Additional changes:
 - in_cksum.[ch]:
   * use a generic C version instead of the assembly version in the !gcc
     case (ASM code breaks with the optimizations icc does)
     -> no bad checksums with an icc compiled kernel
     Help from:		andre, grehan, das
     Stolen from: 	alpha version via ppc version
     The entire checksum code should IMHO be replaced with the DragonFly
     version (because it isn't guaranteed future revisions of gcc will
     include similar optimizations) as in:

Incarnations of this patch survive gcc compiles since a loooong time,
I use it on my desktop. An icc compiled kernel works since Nov. 2003
(exceptions: snd_* if used as modules), it survives a build of the
entire ports collection with icc.
