/*
 * The boot vector table is made up of an array of 1024 elements of
 * struct cvmx_boot_vector_element.  There is one entry for each
 * possible MIPS CPUNum, indexed by the CPUNum.
 *
 * Once cvmx_boot_vector_get() returns a non-NULL value (indicating
 * success), NMI to a core will cause execution to transfer to the
 * target_ptr location for that core's entry in the vector table.
 *
 * The struct cvmx_boot_vector_element fields app0, app1, and app2 can
 * be used by the application that has set the target_ptr in any
 * application specific manner, they are not touched by the vectoring
 * code.
 *
 * The boot vector code clobbers the CP0_DESAVE register, and on
 * OCTEON II and later CPUs also clobbers CP0_KScratch2.  All GP
 * registers are preserved, except on pre-OCTEON II CPUs, where k1 is
 * clobbered.
