dc4ee6ca91 Merge the Cavium Octeon SDK 2.3.0 Simple Executive code and update FreeBSD to
make use of it where possible.

This primarily brings in support for newer hardware, and FreeBSD is not yet
able to support the abundance of IRQs on new hardware and many features in the
Ethernet driver.

Because of the changes to IRQs in the Simple Executive, we have to maintain our
own list of Octeon IRQs now, which probably can be pared-down and be specific
to the CIU interrupt unit soon, and when other interrupt mechanisms are added
they can maintain their own definitions.

Remove unmasking of interrupts from within the UART device now that the
function used is no longer present in the Simple Executive.  The unmasking
seems to have been gratuitous as this is more properly handled by the buses
above the UART device, and seems to work on that basis.

f3318c38dc Revert part of old logic of assigning MAC addressess:
- Reserver respective number of addresses for managment port
- octm uses base address directly
- other drivers get MACs on "first come first served" basis

6cc1d135cd - Add better COP2 (crypto coprocessor) context handler for Octeon. Keep
COP2 disabled and lazily allocate COP2 context structure in exception
    handler. Keep kernel and userland contexts separated.

6b194c7ade - Add generic GPIO driver for Cavium Octeon. At the moment pin definition is
hardcoded but will be changed later with more flexible way to define them.

15fe2454ae o) Expand the CIU driver to be aware of newly-allocated parts of the IRQ range.
o) Add 'octm', a trivial driver for the 10/100 management ports found on some
   Octeon systems.
o) Make the Simple Executive's management port helper routines compile on
   FreeBSD (namely by not doing math on void pointers.)
o) Add a cvmx_mgmt_port_sendm routine to the Simple Executive to send an mbuf
   so there is only one copy in the transmit path, rather than having to first
   copy the mbuf to an intermediate buffer and then copy that to the Simple
   Executive's transmit ring.
o) Properly work out MII addresses of management ports on the Lanner MR-730.
   XXX The MR-730 also needs some patches to the MII read/write routines, but
       this is sufficient for now.  Media detection will be fixed in the future
       when I can spend more time reading the vendor-supplied patches.

04b6fa8330 Merge Cavium Octeon SDK 2.0 Simple Executive; this brings some fixes and new
facilities as well as support for the Octeon 2 family of SoCs.

XXX Note that with our antediluvian assembler, we can't support some Octeon 2
    instructions and fall back to using the old ones instead.

f05957f7c6 o) Make it possible to attach a PHY directly to an octe device rather than
using miibus, since for some devices that use multiple addresses on the bus,
   going through miibus may be unclear, and for devices that are not standard
   MII PHYs, miibus may throw a fit, necessitating complicated interfaces to
   fake the interface that it expects during probe/attach.
o) Make the mv88e61xx SMI interface in octe attach a PHY directly and fix some
   mistakes in the code that resulted from trying too hard to present a nice
   interface to miibus.
o) Add a PHY driver for the mv88e61xx.  If attached (it is optional in kernel
   compiles so the default behavior of having a dumb switch is preserved) it
   will place the switch in a VLAN-tagging mode such that each physical port
   has a VLAN associated with it and interfaces for the VLANs can be created to
   address or bridge between them.
   XXX It would be nice for this to be part of a single module including the
       SMI interface, and for it to fit into a generic switch configuration
       framework and for it to use DSA rather than VLANs, but this is a start
       and gives some sense of the parameters of such frameworks that are not
       currently present in FreeBSD.  In lieu of a switch configuration
       interface, per-port media status and VLAN settings are in a sysctl tree.
   XXX There may be some minor nits remaining in the handling of broadcast,
       multicast and unknown destination traffic.  It would also be nice to go
       through and replace the few remaining magic numbers with macros at some
       point in the future.
   XXX This has only been tested with the MV88E6161, but it should work with
       minimal or no modification on related switches, so support for probing
       them was included.

Thanks to Pat Saavedra of TELoIP and Rafal Jaworowski of Semihalf for their
assistance in understanding the switch chipset.

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.
