    13 The ''boot_init'' function makes the initialisation in two steps:
    14  
    15 The first step is sequencially executed by proc[0][0][0], while other processors are in wait state:
    16  * Physical memory allocators initialisation : ''boot_pmem_init()''
    17  * Page table initialisation : ''boot_ptabs_init()''
    18  * Proc[0][0][0] MMU activation
    19  * Private vobjs initialisation : ''boot_vobjs_init()''
    20  * Schedulers initialisation : ''boot_schedulers init()''
    21  * Peripherals initialisation : ''boot_peripherals_init()''
    22  * Kernel & application code loading : ''boot_elf_load()''
    23  * Start all other processors
    24 The second step is executed in parallel by all processors:
    25  * CP0_SCHED register initialisation
    26  * MMU Activation
    27  * Status Register Initialisation (to use the GIET_VM exception handler).
    28  * Jump to ''kernel_init()''
