[803]	11	# This file contains a mapping generator for the "tsar_generic_leti" platform.
[793]	12	# This includes both the hardware architecture (clusters, processors,
[937]	13	# peripherals, physical space segmentation) and the mapping of all boot
	14	# and kernel objects (global vsegs).
[793]	15	#
[967]	16	# This platform includes 6 external peripherals controllers located
	17	# in cluster[x_size-1][y_size-1]: TTY, IOC, FBF, NIC, CMA, PIC.
	18	# It does not use the IOB component.
[937]	19	# It does not use an external ROM, as the preloader code is (pre)loaded
	20	# at address 0x0, in the physical memory of cluster[0][0].
	21	# It can use an - optional - RAMDISK located in cluster[0][0].
[967]	22	# The upper row (y = y_size-1) does not contain processors or memory.
[937]	23	#
[967]	24	# The "constructor" parameters (defined in Makefile) are:
	25	# - x_size : number of clusters in a row
	26	# - y_size : number of clusters in a column
	27	# - nb_procs : number of processors per cluster
	28	# - nb_ttys : number of TTY channels
[820]	29	# - fbf_width : frame_buffer width = frame_buffer heigth
[967]	30	# - ioc_type : can be 'BDV','HBA','SDC','RDK'
	31	#
	32	# The others hardware parameters (defined below) are:
[793]	33	# - nb_nics : number of NIC channels
[937]	34	# - nb_cmas : number of CMA channels
[967]	35	# - x_io : cluster_io x coordinate
	36	# - y_io : cluster_io y coordinate
	37	# - x_width : number of bits for x coordinate
	38	# - y_width : number of bits for y coordinate
	39	# - paddr_width : number of bits for physical address
[793]	40	# - irq_per_proc : number of input IRQs per processor
[937]	41	# - use_ramdisk : use a RAMDISK when True
[967]	42	# - peri_increment : address increment for replicated vsegs
[820]	43	#
[937]	44	# Regarding the boot and kernel vsegs mapping :
	45	# - We use one big physical page (2 Mbytes) for the preloader and the four
	46	# boot vsegs, all allocated in cluster[0,0].
	47	# - We use the 16 next big pages in cluster[0][0] to implement the RAMDISK.
	48	# - We use one big page per cluster for the replicated kernel code vsegs.
	49	# - We use one big page in cluster[0][0] for the kernel data vseg.
	50	# - We use one big page per cluster for the distributed kernel heap vsegs.
	51	# - We use one big page per cluster for the distributed ptab vsegs.
	52	# - We use small physical pages (4 Kbytes) per cluster for the schedulers.
	53	# - We use one big page for each external peripheral in IO cluster,
	54	# - We use one small page per cluster for each internal peripheral.
