Octeon MAC address

I have several other fields in the sysinfo structure that are not initialized through the minimal_initialize call, and the MAC address (base + count) is one of them. There are also one or two things that could be removed from the call (e.g. clock speed). I don't know that we should muck with the existing call since it is in the SDK; I was thinking of adding a secondary init call for the rest of the fields. At the moment I just manually set these fields for both U-Boot and other bootstrap cases (with basically the same two lines of code you added).
IIRC, the CAPK-0100ND board is correctly called out to set the MAC address offset (to account for the management port), so once you set the base all should be well. I did note that the code that attaches MAC addresses to interfaces does NOT check the count. It "assumes" that you have enough to handle however many interfaces/ports your board declares itself as having.
Your patch is fine. My work extends that to some other fields I trip across, and the non-U-Boot case (which doesn't use the octeon_bootinfo structure).
