Cummulative patch of changes that are not vendor-specific:
	- ARMv6 and ARMv7 architecture support
	- ARM SMP support
	- VFP/Neon support
	- ARM Generic Interrupt Controller driver
	- Simplification of startup code for all platforms

8304b99a75 Create a generic way to support multiple boards within an
arm platform.  Add all the atmel boards to the ATMEL kernel for
testing purposes.  Until boot loader arg parsing of baord type
is done, this won't actually be able to do the runtime selection.

38ac33aa84 Add support for parsing Linux ATAGs such as you'd see from uboot or
redboot.  Support is very preiminary and likely needs some work. Also,
do some minor code shuffling of the FreeBSD /boot/loader metadata
parsing code.  This code is preliminary and should be used with
caution.

0bb13a26f0 Create default_parse_boot_param which, if FreeBSD /boot/loader support
is enabled, sets values based on the metadata passed in.  Otherwise
fake_preload_metadata is called.  Change the default parse_boot_param
to default_parse_boot_param.  Enable this functionality only on the mv
platform, which is where most of the code is from.

537cdfaff1 Eliminate the now-unused AT91C_MASTER_CLOCK option and change the one
place in the source it was used to the more correct AT91C_MAIN_CLOCK.
Sort AT91C_MAIN_CLOCK into a better location in the options.arm file.

208cf1fbc3 - Add new ARM kernel option QEMU_WORKAROUNDS which can be
used in the code which needs to implement some specific
  behaviour when being run under QEMU.
- Make PXA UART probe code to work under QEMU gumstix, which
  doesn't emulate all the ports properly.

db5ef4fc77 Convert Marvell ARM platforms to FDT convention.
The following systems are involved:

  - DB-88F5182
  - DB-88F5281
  - DB-88F6281
  - DB-78100
  - SheevaPlug

This overhaul covers the following major changes:

  - All integrated peripherals drivers for Marvell ARM SoC, which are
    currently in the FreeBSD source tree are reworked and adjusted so they
    derive config data out of the device tree blob (instead of hard coded /
    tabelarized values).

  - Since the common FDT infrastrucutre (fdtbus, simplebus) is used we say
    good by to obio / mbus drivers and numerous hard-coded config data.

Note that world needs to be built WITH_FDT for the affected platforms.

18159f6a49 Introduce MII_ADDR_BASE option on ARM, which allows to override the default
per platform requirements.

Notes:
- Only used by mge(4) at the moment.

- This is very simplified approach and should be replaced by some long-term
  solution for managing the board/platform configuration (among others the
  MAC-PHY binding info).

d212022417 Merge WIP from p4:
o recognize ixp435 cpu
o change memory layout for for ixp4xx to not assume memory is aliases
  to 0x10000000 (Cambria/ixp435 memory starts at zero)
o handle 64 irqs for ixp435
o dual EHCI USB 2.0 controller integral to ixp435
o overhaul NPE code for ixp435 and better MAC+MII naming
o updated NPE firmware (including NPE-A image for ixp435/ixp465)
o Gateworks Cambria board support:
  - IDE compact flash
  - MCU
  - front panel LED on i2c bus
  - Octal LED latch

Sanity-tested with NFS-root on Avila and Cambria boards.  Requires
pending boot2 mods for CF-boot on Cambria.

373bbe25ff Introduce basic support for Marvell families of system-on-chip ARM devices:
*  Orion
     - 88F5181
     - 88F5182
     - 88F5281

  * Kirkwood
     - 88F6281

  * Discovery
     - MV78100

The above families of SOCs are built around CPU cores compliant with ARMv5TE
instruction set architecture definition. They share a number of integrated
peripherals. This commit brings support for the following basic elements:

  * GPIO
  * Interrupt controller
  * L1, L2 cache
  * Timers, watchdog, RTC
  * TWSI (I2C)
  * UART

Other peripherals drivers will be introduced separately.

9722a61504 Support for the XScale PXA255 SoC as found on the Gumstix Basix and Connex
boards.  This is enough to net-boot to multiuser.

Also supported is the SMSC LAN91C111 parts used on the netCF, netDUO and netMMC
add-on boards.

I'll be putting some instructions on how to boot this on the Gumstix boards
online soon.

This is still fairly rough and will be refined over time but I felt it was
better to get this out there where other people can help out.

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.

d5d776c16b Resurrect Skyeye support :
Add a new option, SKYEYE_WORKAROUNDS, which as the name suggests adds
workarounds for things skyeye doesn't simulate. Specifically :
- Use USART0 instead of DBGU as the console, make it not use DMA, and           manually provoke an interrupt when we're done in the transmit function.
- Skyeye maintains an internal counter for clock, but apparently there's
no way to access it, so hack the timecounter code to return a value which
is increased at every clock interrupts. This is gross, but I didn't find a
better way to implement timecounters without hacking Skyeye to get the
counter value.
- Force the write-back of PTEs once we're done writing them, even if they
are supposed to be write-through. I don't know why I have to do that.
