/* * 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. *

/* * Applications install the boot bus code in cvmx-boot-vector.c, which * uses this magic:
