 == __Y) Boot-loader functions__ ==
 
+The ''boot_init'' function makes the initialisation in two steps:
+ 
+The first step is sequencially executed by proc[0][0][0], while other processors are in wait state:
+ * Physical memory allocators initialisation : ''boot_pmem_init()''
+ * Page table initialisation : ''boot_ptabs_init()''
+ * Proc[0][0][0] MMU activation
+ * Private vobjs initialisation : ''boot_vobjs_init()''
+ * Schedulers initialisation : ''boot_schedulers init()''
+ * Peripherals initialisation : ''boot_peripherals_init()''
+ * Kernel & application code loading : ''boot_elf_load()''
+ * Start all other processors
+The second step is executed in parallel by all processors:
+ * CP0_SCHED register initialisation
+ * MMU Activation 
+ * Status Register Initialisation (to use the GIET_VM exception handler).
+ * Jump to ''kernel_init()'' 
+
