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.

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.
