7// The MAPPING_INFO data structure can be used with the GIET.
8// It contains the mapping directive for one or several virtual spaces.
9// Ech virtual space contains a variable number of virtual segments
10// and a variable number of tasks. The number of virtual space can be one.
11//
12// The mapping table data structure is organised as the concatenation of
13// a fixed size header, and 6 variable size arrays:
14//
15// - mapping_cluster_t  cluster[] 
16// - mapping_pseg_t     pseg[]       
17// - mapping_vspace_t   vspace[] 
18// - mapping_vseg_t     vseg[]     
19// - mapping_vseg_t     vobj[]   
20// - mapping_task_t     task[] 
21// - mapping_irq_t      irq[irqs]   
22// - mapping_coproc_t   coproc[]
23// - mapping_cp_port_t  cp_port[]
24// - mapping_periph_t   periph[]
25//
26// It is intended to be stored in the boot ROM at address MAPPING_BOOT_BASE.
