MIPS: OCTEON: Extend number of supported CPUs past 32
To support more than 48 CPUs, the bootinfo structure grows a new
coremask structure. Add the definition of the structure and add it to
struct cvmx_bootinfo. In prom_init(), copy the new coremask data into
the sysinfo structure, and use it in smp_setup().
