9c1fcf4ecd 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.

3693ee3c32 Switch to ath hal source code. Note this removes the ath_hal
module; the ath module now brings in the hal support.  Kernel
config files are almost backwards compatible; supplying

device ath_hal

gives you the same chip support that the binary hal did but you
must also include

options AH_SUPPORT_AR5416

to enable the extended format descriptors used by 11n parts.
It is now possible to control the chip support included in a
build by specifying exactly which chips are to be supported
in the config file; consult ath_hal(4) for information.

9d3bb599b1 - bump __FreeBSD version to reflect added buf_ring, memory barriers,
and ifnet functions

- add memory barriers to <machine/atomic.h>
- update drivers to only conditionally define their own

- add lockless producer / consumer ring buffer
- remove ring buffer implementation from cxgb and update its callers

- add if_transmit(struct ifnet *ifp, struct mbuf *m) to ifnet to
  allow drivers to efficiently manage multiple hardware queues
  (i.e. not serialize all packets through one ifq)
- expose if_qflush to allow drivers to flush any driver managed queues

745c5c702f Initial support of loader(8) for ARM machines running U-Boot.
This uses the common U-Boot support lib (sys/boot/uboot, already used on
FreeBSD/powerpc), and assumes the underlying firmware has the modern API for
stand-alone apps enabled in the config (CONFIG_API).

Only netbooting is supported at the moment.

  * DB-88F6281, RD-88F6281 (Kirkwood based)

3226c13778 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.

e725b1fa27 Do not use cached page for temporary mapping in pmap_zero_page_generic()
The physical page which we clear is accessed via additional temp kernel
mapping for the period of zeroing operation. However in systems with virtual
d-cache (most ARMs) when write-allocate feature is enabled, we can have
modified but unflushed content pertaining to this physical page still in the
d-cache due to its primary (pre-existing) mapping. In such scenario that
cached content upon flush is likely to overwrite [portions of] the physical
page we want to zero here..

This is a general problem with multiple virtual mappings covering the same
physical page with write-allocate and virtual d-cache: there is inherent
potential for corruptions of this kind, which are not easily resolved; it is
best policy that such multiple mappings be not allowed.
