8	// This file define a generic TSAR architecture without virtual memory.
9	// - It uses vci_local_crossbar as local interconnect
10	// - It uses virtual_dspin as global interconnect
11	// - It uses the vci_cc_xcache_wrapper_v4
12	// - It uses the vci_mem_cache_v4
13	// - It uses the vci_xicu, with one vci_multi_tty, and one
14	// vci_multi_dma controlers per cluster.
15	// The physical address space is 32 bits.
16	// The number of clusters cannot be larger than 256.
17	// The number of processors per cluster cannot be larger than 4.
18	// The parameters must be power of 2.
19	// - xmax : number of clusters in a row
20	// - ymax : number of clusters in a column
21	// - nprocs : number of processors per cluster
22	//
23	// The peripherals BDEV, FBUF, and the boot BROM
24	// are in the cluster containing address 0xBFC00000.
25	// - The nprocs TTY IRQs are connected to IRQ_IN[0] to IRQ_IN[3]
26	// - The nprocs DMA IRQs are connected to IRQ_IN[4] to IRQ_IN[7]
27	// - The IOC IRQ is connected to IRQ_IN[8]
28	//
29	// General policy for 32 bits address decoding in direct space:
30	// All segments base addresses are multiple of 64 Kbytes
31	// Therefore the 16 address MSB bits completely define the target:
32	// The (x_width + y_width) MSB bits (left aligned) define
33	// the cluster index, and the 8 LSB bits define the local index:
34	//
35	// \| X_ID \| Y_ID \|---\| LADR \| OFFSET \|
36	// \|x_width\|y_width\|---\| 8 \| 16 \|
37	//
38	// Half of all clusters being in the protected address space domain
39	// (addresses larger than 0x8000000), software must execute in
40	// kernel mode to access memory if we want to exploit locality,
41	// because some stacks and heaps will be in the protected domain.
