    v40 v41  
    8181== __Y) Boot-loader functions__ ==
    8282
     83The ''boot_init'' function makes the initialisation in two steps:
     84 
     85The first step is sequencially executed by proc[0][0][0], while other processors are in wait state:
     86 * Physical memory allocators initialisation : ''boot_pmem_init()''
     87 * Page table initialisation : ''boot_ptabs_init()''
     88 * Proc[0][0][0] MMU activation
     89 * Private vobjs initialisation : ''boot_vobjs_init()''
     90 * Schedulers initialisation : ''boot_schedulers init()''
     91 * Peripherals initialisation : ''boot_peripherals_init()''
     92 * Kernel & application code loading : ''boot_elf_load()''
     93 * Start all other processors
     94The second step is executed in parallel by all processors:
     95 * CP0_SCHED register initialisation
     96 * MMU Activation
     97 * Status Register Initialisation (to use the GIET_VM exception handler).
     98 * Jump to ''kernel_init()''
     99
