a22b69b772 o) Allow devices to override the MDIO read and write functions presented to
the miibus attached to octe interfaces.
o) Add an SMI/MDIO interface to the MV88E61XX and use it for the switch PHY on
   the Lanner MR-320.  An actual driver for the switch PHY will come later.
   Note that for now it intercepts and fakes MII_BMSR reads to prevent the
   miibus from talking to anything but the switch itself.

709d8161a6 Make the vast majority of Simple Executive files standard. Perhaps some of
these could be made dependent on either of the octusb or octe options, but
making them standard fixes a number of option combinations that were previously
broken.

bfa39fa09f o) Add the "octusb" controller which supports the first port of the Octeon
on-board USB controller.  It is not currently enabled because there are
   known problems with device communication and until those are fixed I am not
   certain that it won't destabilize the system. [1]
o) Add the "cryptocteon" opencrypto device based on the OCF device written by
   David McCullough.  It is not currently enabled because until support for
   saving/restoring coprocessor 2 state on context switch is available, it runs
   with interrupts disabled, which tends to pessimize performance over using a
   software crypto facility.  Tests using this driver which are not negatively
   affected by it running with interrupts disabled show it to be substantially
   faster than software for large blocks.

cea2b8b915 Update the port of FreeBSD to Cavium Octeon to use the Cavium Simple Executive
library:
o) Increase inline unit / large function growth limits for MIPS to accommodate
   the needs of the Simple Executive, which uses a shocking amount of inlining.
o) Remove TARGET_OCTEON and use CPU_CNMIPS to do things required by cnMIPS and
   the Octeon SoC.
o) Add OCTEON_VENDOR_LANNER to use Lanner's allocation of vendor-specific
   board numbers, specifically to support the MR320.
o) Add OCTEON_BOARD_CAPK_0100ND to hard-wire configuration for the CAPK-0100nd,
   which improperly uses an evaluation board's board number and breaks board
   detection at runtime.  This board is sold by Portwell as the CAM-0100.
o) Add support for the RTC available on some Octeon boards.
o) Add support for the Octeon PCI bus.  Note that rman_[sg]et_virtual for IO
   ports can not work unless building for n64.
o) Clean up the CompactFlash driver to use Simple Executive macros and
   structures where possible (it would be advisable to use the Simple Executive
   API to set the PIO mode, too, but that is not done presently.)  Also use
   structures from FreeBSD's ATA layer rather than structures copied from
   Linux.
o) Print available Octeon SoC features on boot.
o) Add support for the Octeon timecounter.
o) Use the Simple Executive's routines rather than local copies for doing reads
   and writes to 64-bit addresses and use its macros for various device
   addresses rather than using local copies.
o) Rename octeon_board_real to octeon_is_simulation to reduce differences with
   Cavium-provided code originally written for Linux.  Also make it use the
   same simplified test that the Simple Executive and Linux both use rather
   than our complex one.
o) Add support for the Octeon CIU, which is the main interrupt unit, as a bus
   to use normal interrupt allocation and setup routines.
o) Use the Simple Executive's bootmem facility to allocate physical memory for
   the kernel, rather than assuming we know which addresses we can steal.
   NB: This may reduce the amount of RAM the kernel reports you as having if
       you are leaving large temporary allocations made by U-Boot allocated
       when starting FreeBSD.
o) Add a port of the Cavium-provided Ethernet driver for Linux.  This changes
   Ethernet interface naming from rgmxN to octeN.  The new driver has vast
   improvements over the old one, both in performance and functionality, but
   does still have some features which have not been ported entirely and there
   may be unimplemented code that can be hit in everyday use.  I will make
   every effort to correct those as they are reported.
o) Support loading the kernel on non-contiguous cores.
o) Add very conservative support for harvesting randomness from the Octeon
   random number device.
o) Turn SMP on by default.
o) Clean up the style of the Octeon kernel configurations a little and make
   them compile with -march=octeon.
o) Add support for the Lanner MR320 and the CAPK-0100nd to the Simple
   Executive.
o) Modify the Simple Executive to build on FreeBSD and to build without
   executive-config.h or cvmx-config.h.  In the future we may want to
   revert part of these changes and supply executive-config.h and
   cvmx-config.h and access to the options contained in those files via
   kernel configuration files.
o) Modify the Simple Executive USB routines to support getting and setting
   of the USB PID.

b6777295a6 o) Add SMP support for Octeon using U-Boot to launch all the processors at the
same time.
o) Remove some unused trivial uart functions from octeon_machdep now that the
   uart part is fully working and they are unused.
o) Use __func__ instead of __FUNCTION__.
o) Use intr_*() instead of other routines that do the same thing.
o) Remove some duplicate printfs from the Octeon port, as well as duplicate
   setting of Maxmem.
o) Use the right frequency divider on Octeon.
o) Use PCPU_GET(cpuid) consistently to get the cpuid of the running core.
o) Remove some unused macros in the Octeon port.
o) Use mips_sync() around use of the global dpcpu, whose value may not be
   visible to APs at first.
o) When loading the first thread's stack, use macros to make the code correct
   for n64 as well.
o) Remove stub, do-nothing FAU init/enable/disable functions from the RGMX
   driver.

6b06709221 Merge from projects/mips to head by hand:
Copy the support files for the Octeon 1 CPU from sys/mips/octeon1 on
the projects/mips side to sys/mips/cavium on the head side to conform
to the other vendor code.  This code was contributed by Cavium to the
project and forward ported by Warner Losh, with some additional code
from Randal Stewart.

# I'll fix the building problems the move creates in a future commit.
