5308af6337 o) Unmask Central Interrupt Unit interrupts on APs, too.
o) There's no good reason to make the low bits of the ebase the core
   number.  While per-CPU exception bases would be nice, for now we just
   need to make ebase the same on all cores.

1dadcedcfc When allocating memory from bootmem for the kernel to use, try to leave about
2MB of memory in the bootmem allocator for the SDK to use internally at a later
point.  It'd be nice if there were some functions we could call before
allocating memory to let various facilities reserve some memory, but for now
this seems sufficient.  Previously some unfortunate systems could give up all
(or at least most) of their memory to the kernel from bootmem, and then
allocating command queues for packet output and the like would fail later in
the boot process (which in turn would lead to crashes even later.)

b8248487b3 Don't free the work queue entry that we're using to hold the scatter-gather
list on exit from the transmit path.  The scatter-gather list itself can be
asynchronously DMAed to the transmit hardware, and we could actually lock up
the transmitter if any of a number of races around this were lost.

Instead, let the PKO free the scatter-gather list when it is done with it, and
use the "i" bit in each segment of the packet to avoid having them go into the
FPA.

This fixes an unrecoverable transmit stall under transmit load.

8e5d93dbb4 Convert the PHY drivers to honor the mii_flags passed down and convert
the NIC drivers as well as the PHY drivers to take advantage of the
mii_attach() introduced in r213878 to get rid of certain hacks. For
the most part these were:
- Artificially limiting miibus_{read,write}reg methods to certain PHY
  addresses; we now let mii_attach() only probe the PHY at the desired
  address(es) instead.
- PHY drivers setting MIIF_* flags based on the NIC driver they hang
  off from, partly even based on grabbing and using the softc of the
  parent; we now pass these flags down from the NIC to the PHY drivers
  via mii_attach(). This got us rid of all such hacks except those of
  brgphy() in combination with bce(4) and bge(4), which is way beyond
  what can be expressed with simple flags.

While at it, I took the opportunity to change the NIC drivers to pass
up the error returned by mii_attach() (previously by mii_phy_probe())
and unify the error message used in this case where and as appropriate
as mii_attach() actually can fail for a number of reasons, not just
because of no PHY(s) being present at the expected address(es).

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.

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.

41341ca726 Rather than shifting offsets by three, set register offset to 3. All our
bus interface does that's special here now is to use a 64-bit register size.
In theory, uart(4) ought to support a regsz as well as regshft and support
64-bit registers directly.

Also use the UART class's range rather than a hand-coded 1024 for the address
range.

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.
