230291dbf1 Add in the AP96 phy configuration from openwrt.
* arge0 doesn't (yet) work via the switch PHY ports; I'm not sure why.
* arge1 maps to the WAN port. That works.

TODO:

* The PLL register needs a different (non-default) value for Gigabit
  Ethernet.  The board setup code needs to be extended a bit to allow
  for non-default pll_1000 values - right now, those values come out
  of hard-coded values in the per-chip set_pll_ge() routines.

66d589b127 The AR913x MII speed configuration matches the AR71xx MII configuration.
So share the code.

Don't do it for the AR724x - that has a completely different set of PLL
and MII configuration parameters.

018271e496 Introduce configuration files for AP94 and AP96.
This uses the new firmware(9) method for squirreling away the EEPROM
contents from SPI flash so ath(4) can get to them later.

It won't work out of the box just yet - you have to add this to
if_ath_pci.c:

#define ATH_EEPROM_FIRMWARE

.. until I've added it as a configuration option and updated things.

6b1a85efd5 (ab)Use the firmware API to store away EEPROM calibration data for
future use by the ath(4) driver.

These embedded devices put the calibration/PCI bootstrap data on the
on board SPI flash rather than on an EEPROM connected to the NIC.
For some boards, there's two NICs and two sets of EEPROM data in the
main SPI flash.

The particulars:

* Introduce ath_fixup_size, which is the size of the EEPROM area in
  bytes.
* Create a firmware image with a name based on the PCI device identifier
  (bus/slot/device/function).
* Hide some verbose debugging behind 'bootverbose'.

ath(4) can then use this to load in the EEPROM data.

This requires AR71XX_ATH_EEPROM to be defined.

10450b4fc3 Sync this code against what's in OpenWRT trunk.
* the openwrt code doesn't treat 0/0/0 any differently
  from other bus/slot/func combinations.
* A "local write" function writes to the LCONF area, and
  so I've added it.
* The PCI workaround at attach time uses this LCONF code,
  which it already did ..
* .. but it is a 4 byte write, not a 2 byte write.
  Even though it's PCIR_COMMAND which is a two byte PCI register.

74a66a0c1f Reinstate the XTLB handler for CPU_NLM and CPU_RMI
These platforms set the KX bit even when booted in 32 bit mode. So
the XLTB handler is needed even when __mips_n64 is not defined.

4544b2987d Assume a big-endian default on MIPS and drop the "eb" suffix from MACHINE_ARCH.
This makes our naming scheme more closely match other systems and the
expectations of much third-party software.  MIPS builds which are little-endian
should require and exhibit no changes.  Big-endian TARGET_ARCHes must be
changed:
	From:		To:
	mipseb		mips
	mipsn32eb	mipsn32
	mips64eb	mips64

An entry has been added to UPDATING and some foot-shooting protection (complete
with warnings which should become errors in the near future) to the top-level
base system Makefile.

5edfb77dd3 Add software PMC support.
New kernel events can be added at various location for sampling or counting.
This will for example allow easy system profiling whatever the processor is
with known tools like pmcstat(8).

Simultaneous usage of software PMC and hardware PMC is possible, for example
looking at the lock acquire failure, page fault while sampling on
instructions.

8374f23681 Resource allocation for XLP SoC SDHCI slots
The on-chip SD slots do not have PCI BARs corresponding to them, so
this has to be handled in the custom SoC memory allocation.

0ec682f566 Update memory and resource allocation code for SoC devices
The XLP on-chip devices have PCI configuration headers, but some of the
devices need custom resource allocation code.
- devices with no MEM/IO BARs with registers in PCIe extended reg
  space have to be handled in memory resource allocation
- devices without INTPIN/INTLINE in PCI header can be supported
  by having these faked with a shadow register.
- Some devices does not allow 8/16 bit access to the register space,
  he default bus space cannot be used for these.

Subclass pci and override attach and resource allocation methods to
take care of this.

Remove earlier code which did this partially.

- fix SoC device resource allocation code
- Do not use '|' while updating PCIE_BRIDGE_MSI_ADDRL

619ab2327e Remove pty(4) from our kernel configurations.
As of FreeBSD 8, this driver should not be used. Applications that use
posix_openpt(2) and openpty(3) use the pts(4) that is built into the
kernel unconditionally. If it turns out high profile depend on the
pty(4) module anyway, I'd rather get those fixed. So please report any
issues to me.

The pty(4) module is still available as a kernel module of course, so a
simple `kldload pty' can be used to run old-style pseudo-terminals.

7910492ee4 Begin fleshing out MII clock rate configuration changes.
These are needed for some particular port configurations where the default
speed isn't suitable for all link speed types. (Ie, changing 10/100/1000MBit
PLL rate requires a similar MII clock rate, rather than a fixed MII rate.)

This is:

* only currently implemented for the ar71xx;
* isn't used anywhere (yet), as the final interface for this hasn't yet
  been determined.
