FreeBSD on MIPS64 (Cavium Octeon III)

Greetings,

I have recently acquired some hardware based on Cavium Octeon III (CN70XX - ITUS Networks Shield), and I would like to try and install FreeBSD on it :)

I am new to FreeBSD (and kernel compiling in general) so apologies if this is a stupid question, but I have read the parts of the handbook which have got me this far.

* Is there any support for Octeon III processors in the kernel?

* I have attempted to build an image using the standard OCTEON1 kernel config, just using the auto-detect at runtime for a test and when it boots from uboot I get the following error.

Code:
reading kernel/kernel
9974466 bytes read in 9068 ms (1 MiB/s)
argv[2]: mem=0
argv[3]: numcores=2
Allocating memory for ELF segment: addr: 0xffffffff80100080 (adjusted to: 0x100080), size0x88b440
## Loading big-endian Linux kernel with entry point: 0xffffffff80100080 ...
Bootloader: Done loading app on coremask: 0x3

Using runtime CPU model checks.
CPU Model: CNXXXXpX.X-3150-XXX
CPU clock: 1000MHz  Core Mask: 0x3

MAC address base: 2c:26:5f:80:0a:40 (3 configured)
panic: mips_get_identity: unsupported Cavium Networks CPU.
cpuid = 0
Uptime: 1s
* I have looked in the sys/contrib/octeon-sdk/octeon-model.h to see if there is a specific value for the CPU model I am using but the closest matches are as follows

Code:
#define OCTEON_CNF71XX_PASS1_0  0x000d9400
#define OCTEON_CNF71XX  (OCTEON_CNF71XX_PASS1_0 | OM_IGNORE_REVISION)
#define OCTEON_CNF71XX_PASS1_X  (OCTEON_CNF71XX_PASS1_0 | OM_IGNORE_MINOR_REVISION)
* None of these are exact matches, is there a particular one I should try and use?

Any tips much appreciated.

This is an old post but I hope someone could tell me if there is a way I can build FreeBSD for octeon CN70XX/CN71XX?
It seems SDK in sys/contrib/octeon-sdk in FreeBSD 11.1 is too old, octeon-model.h does not have CN70XX model defined.
