aeefab2b98 Remove the hardcoded IXP425_UART?_VBASE values in the
uart_ixp425_probe() and uart_cpu_getdev(). Change
uart_cpu_getdev() to use hints to find the console.

728c8470f1 We do not need to get the irq out of ivars in ixp425_setup_intr(). By
this time they have already been set. In fact trying to set it here too
breaks irqs for pci devices.

56b5a9c2a7 Search for a proper ucode image to use by incrementing the minor
release number up to the max.  This should eliminate the need to
tweak the default imageid define for later releases that are found

640edef54d Move to hints for configuring numerous devices so we can eliminate various
quirky code: uarts, led, cf/ide, ixpqmgr, npe are now specified with hints.

May want to put some of these devices back in the code and just use hints
to override/specify configuration.

dbbeaafca4 Don't muck with the internal state of a uart during probe, all we
should setup is the class.  This corrects an issue where enabling
uart1 on the avila board caused uart0 to stop working during boot
(no msgs generated by rc scripts were displayed).

f8100ce2a7 Don't expose the uart_ops structure directly, but instead have
it obtained through the uart_class structure. This allows us
to declare the uart_class structure as weak and as such allows
us to reference it even when it's not compiled-in.
It also allows is to get the uart_ops structure by name, which
makes it possible to implement the dt tag handling in uart_getenv().
The side-effect of all this is that we're using the uart_class
structure more consistently which means that we now also have
access to the size of the bus space block needed by the hardware
when we map the bus space, eliminating any hardcoding.

f29fa1dfa4 Revisit the watchdogs: Resetting the error to EINVAL after failing to set the
watchdog might hide the succesful arming of an earlier one. Accept that on
failing to arm any watchdog (because of non-supported timeouts) EOPNOTSUPP is
returned instead of the more appropriate EINVAL.

33d5497079 Cleanup and document the implementation of firmware(9) based on
a version that i posted earlier on the -current mailing list,
and subsequent feedback received.

The core of the change is just in sys/firmware.h and kern/subr_firmware.c,
while other files are just adaptation of the clients to the ABI change
(const-ification of some parameters and hiding of internal info,
so this is fully compatible at the binary level).

In detail:
- reduce the amount of information exported to clients in struct firmware,
  and constify the pointer;

- internally, document and simplify the implementation of the various
  functions, and make sure error conditions are dealt with properly.

The diffs are large, but the code is really straightforward now (i hope).

Note also that there is a subtle issue with the implementation of
firmware_register(): currently, as in the previous version, we just
store a reference to the 'imagename' argument, but we should rather
copy it because there is no guarantee that this is a static string.
I realised this while testing this code, but i prefer to fix it in
a later commit -- there is no regression with respect to the past.

Note, too, that the version in RELENG_6 has various bugs including
missing locks around the module release calls, mishandling of modules
loaded by /boot/loader, and so on, so an MFC is absolutely necessary
there.  I was just postponing it until this cleanup to avoid doing
things twice.

ebfaa05056 Create bus dma tags for both the PCI bus and the IXP425 root bus. Set the
PCI bus' one as the default one, and explicitely use the other one for
non-PCI devices.
This is needed because the PCI bus can only address 64MB of RAM, while some
IXP425 boards have 128MB or more, and most of the PCI drivers do not bother
providing the parent dma tag.

9079fff550 Align the interfaces for the various watchdogs and make the interface
behave as expected.

Also:
- Return an error if WD_PASSIVE is passed in to the ioctl as only
  WD_ACTIVE is implemented at the moment. See sys/watchdog.h for an
  explanation of the difference between WD_ACTIVE and WD_PASSIVE.
- Remove the I_HAVE_TOTALLY_LOST_MY_SENSE_OF_HUMOR define. If you've
  lost your sense of humor, than don't add a define.

Specific changes:

i80321_wdog.c
  Don't roll your own passive watchdog tickle as this would defeat the
  purpose of an active (userland) watchdog tickle.

ichwd.c / ipmi.c:
  WD_ACTIVE means active patting of the watchdog by a userland process,
  not whether the watchdog is active. See sys/watchdog.h.

kern_clock.c:
  (software watchdog) Remove a check for WD_ACTIVE as this does not make
  sense here. This reverts r1.181.

81319550dd Handle a missing NPE firmware file better; if it's missing print a
(somewhat) meaningful message and terminate the build.  It'd be
nice to print a proper URL from which to fetch the file but that

ad1e7d285a Threading cleanup.. part 2 of several.
Make part of John Birrell's KSE patch permanent..
Specifically, remove:
Any reference of the ksegrp structure. This feature was
never fully utilised and made things overly complicated.
All code in the scheduler that tried to make threaded programs
fair to unthreaded programs.  Libpthread processes will already
do this to some extent and libthr processes already disable it.

Also:
Since this makes such a big change to the scheduler(s), take the opportunity
to rename some structures and elements that had to be moved anyhow.
This makes the code a lot more readable.

The ULE scheduler compiles again but I have no idea if it works.

The 4bsd scheduler still reqires a little cleaning and some functions that now do
ALMOST nothing will go away, but I thought I'd do that as a separate commit.

Tested by David Xu, and Dan Eischen using libthr and libpthread.

49953e11d7 Rewrite ARM_USE_SMALL_ALLOC so that instead of the current behavior, it maps
whole the physical memory, cached, using 1MB section mappings. This reduces
the address space available for user processes a bit, but given the amount of
memory a typical arm machine has, it is not (yet) a big issue.
It then provides a uma_small_alloc() that works as it does for architectures
which have a direct mapping.
