3d844eddb7 bus_add_child: change type of order parameter to u_int
This reflects actual type used to store and compare child device orders.
Change is mostly done via a Coccinelle (soon to be devel/coccinelle)
semantic patch.
Verified by LINT+modules kernel builds.

813b73a5a9 Migrate if_arge to use the PLL cpuops.
This has been lightly tested on the AR7161 and AR9132.

303fea5cdc Implement PLL generalisation in preparation for use in if_arge.
* Add a function to write to the relevant PLL register
* Break out the PLL configuration for the AR71XX into the CPU ops,
  lifted from if_arge.c.
* Add the AR91XX PLL configuration ops, using the AR91XX register
  definitions.

c4df93502d Add some initial AR724X chipset support.
This is untested but should at least allow an AR724X to boot.

The current code is lacking the detail needed to expose the PCIe bus.
It is also lacking any NIC, PLL or flush/WB code.

f3135331c6 Add initial Atheros AR91XX support.
This works well enough to bring a system up to single-user mode
using an MDROOT.

Known Issues:

* The EHCI USB doesn't currently work and will panic the kernel during
  attach.
* The onboard ethernet won't work until the PLL routines have been
  fleshed out and shoe-horned into if_arge.
* The WMAC device glue (and quite likely the if_ath support)
  hasn't yet been implemented.

70bd9230d1 Preparation work for supporting the AR91xx and AR724x.
* Implement a SoC probe function, from Linux, which determines the
  SoC family, type and revision. This only probes the AR71xx series
  SoC and (currently) panics on others.

* Migrate some of the AR71XX specific hardware init (USB device, determining
  system frequencies) into using the cpuops introduced in an earlier commit.
  Other SoC specific hardware stuff (per-device flush/WB, GPIO pin wiring,
  Ethernet PLL setup, other things I've likely missed) will be introduced in
  subsequent commits.

4d843b15ca Bring over the first cut of the Atheros-specific SoC operations.
Each of these SoCs have different devices, different hardware initialisation
methods and, quite likely, different quirks. These functions will abstract
out the SoC differences and keep these differences out of the drivers (eg
USB init, if_arge, etc.)

ef54d27641 Address PR kern/148307 - fix if_ath TX mbuf alignment/size constraint checks
The existing code only checked the alignment of the first mbuf and
didn't enforce the size constraints.

This commit introduces a simple function to check the alignment and
size of all mbufs in the list. This fixes the initial issue in the
PR.

queue length. The default value for this parameter is 50, which is
quite low for many of today's uses and the only way to modify this

3f907e3338 Does 4 things:
1) Adds future RMI directories
2) Places intr_machdep.c in specfic files.arch pointing to the generic
   intr_machdep.c.  This allows us to have an architecture dependant intr_machdep.c
   (which we will need for RMI) in the machine specific directory
3) removes intr_machdep.c from files.mips
4) Adds some TARGET_XLR_XLS ifdef's for the machine specific intra_machdep.h. We
   may need to look at finding a better place to put this. But first I want to
   get this thing compiling.

* In arge_attach(), hard reset the MAC blocks before configuring the MAC.
 * In arge_reset_dma(), clear pending packet interrupts based off
   the hardware counter instead of acking every packet in the ring,
   as the hardware counter can exceed the ring size. If the reset
   was successful the counters will be zero anyway.
 * In arge_encap(), remove an unused variable.
 * In arge_tx_locked(), remove redundant setting of the EMPTY flag as
   the TX DMA engine sets it for us.
 * In arge_intr(), remember to clear the interrupt status bits
   relayed from arge_intr_filter().
 * Handle RX overflow and TX underflow.
 * In arge_tx_intr(), remember to unmask the TX interrupt bits
   after processing them.
