This patchset adds the platforms specific bootoctlinux command, which is used to boot the MIPS Octeon Linux kernel (4.9.x). A special command is necessary here, as very platform specific data is passed to the kernel via the bootinfo / bootmem format. This patchset also includes various required infrastructure code for this (octeon-feature, coremask, bootinfo). The code for booting the additional cores is also included in this patchset.
Tested on Octeon 7304 EBB with all 16 cores.
Thanks, Stefan
