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.

4699b5e472 Remove octeon_bootinfo from all files except octeon_machdep.c.
Use instead cvmx_sysinfo_get() consistently.

2873abdc12 Partially revert r224661:
octeon_ap_boot is not a bitmask. It holds the CPU Id of the
AP currently being started. As such there's no need to make
it a 64-bit integral and we're not limited to 64 CPUs.

841fed3aa3 Make octeon_ap_boot 64 bits to handle MAXCPU up to 64.
Better construction of CPU mask in platform_cpu_mask().
Release cores still in reset when platform_start_ap() is called.

f89d6b3f06 Fix a brain-o in platform_cpu_mask() by just specifying a possible
cpuset_t to be copied, rather than return the array.
I can't rely anymore on this being a simple int/long object.

1591f3f18c Allow the platform code to return a bitmask of running cores rather than just
a number of cores, this allows for a sparse set of CPUs.  Implement support
for sparse core masks on Octeon.

XXX jeff@ suggests that all_cpus should include cores that are offline or
    running other applications/OSes, so the platform API should be further
    extended to allow us to set all_cpus to include all cores that are
    physically-present as opposed to only those that are running FreeBSD.

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.

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.

5f3173b517 o) Fix XKPHYS physical address extraction. Also define cache coherency
attributes for XKPHYS.
o) Make coprocessor 0 accessor function macros for register+selector registers
   take the full name so that e.g. (as done in this commit), prid selector 1
   can be written through mips_wr_ebase() rather than mips_wr_prid1().
o) Allow for sign extension of 32-bit segment addresses.
o) Remove an unused MIPS-I register number.

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.
