[802]	11	# This file contains a mapping generator for the "tsar_generic_iob" platform.
[707]	12	# This includes both the hardware architecture (clusters, processors, peripherals,
[938]	13	# physical space segmentation) and the mapping of all boot and kernel objects
	14	# (global vsegs).
[714]	15	#
[966]	16	# This platform includes 7 external peripherals, accessible through an IOB
[938]	17	# components located in cluster [0,0] or in cluster [x_size-1, y_size-1].
[966]	18	# Available peripherals are: TTY, IOC, FBF, ROM, NIC, CMA, PIC.
[938]	19	#
	20	# All clusters contain (nb_procs) processors, one L2 cache, one XCU, and
[972]	21	# one optional hardware coprocessor connected to a MWMR_DMA controller.
[938]	22	#
[966]	23	# The "constructor" parameters (defined in Makefile) are:
[714]	24	# - x_size : number of clusters in a row
	25	# - y_size : number of clusters in a column
	26	# - nb_procs : number of processors per cluster
[874]	27	# - nb_ttys : number of TTY channels
[817]	28	# - fbf_width : frame_buffer width = frame_buffer heigth
[1002]	29	# - ioc_type : can be 'BDV','HBA','SDC', 'SPI' but not 'RDK'
[1025]	30	# - mwr_type : coprocessor type / can be 'GCD','DCT','CPY','NONE'
[714]	31	#
[972]	32	# The other hardware parameters (defined in this script) are:
[714]	33	# - nb_nics : number of NIC channels
[938]	34	# - nb_cmas : number of CMA channels
[714]	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
[1025]	39	# - p_width : number of bits for processor local index
[714]	40	# - paddr_width : number of bits for physical address
	41	# - irq_per_proc : number of input IRQs per processor
[1025]	42	# - peri_increment : address increment for replicated peripherals
[817]	43	#
[938]	44	# Regarding the boot and kernel vsegs mapping :
[1026]	45	# - We use one big physical page (2 Mbytes) for the preloader,
	46	# the 4 boot vsegs are packed in one BPP allocated in cluster[0,0].
	47	# - We use one BPP per cluster for the replicated kernel code vsegs.
	48	# - We use one BPP in cluster[0][0] for the kernel data vseg.
	49	# - We use two BPP per cluster for the distributed kernel heap vsegs.
	50	# - We use one BPP per cluster for the distributed ptab vsegs.
	51	# - We use two SPP per cluster for each schedulers.
	52	# - We use one PBB for each external peripheral in IO cluster,
	53	# - We use one SPP per cluster for each internal peripheral.
