8	// This file define a generic TSAR architecture without virtual memory.
9	// - It uses the vci_vgmn as global interconnect
10	// - It uses the vci_local_crossbar as local interconnect
11	// - It uses the vci_cc_xcache (No MMU)
12	// The physical address space is 32 bits.
13	// The number of clusters cannot be larger than 256.
14	// The three parameters are
15	// - xmax : number of clusters in a row
16	// - ymax : number of clusters in a column
17	// - nprocs : number of processor per cluster
18	//
19	// Each cluster contains nprocs processors, one Memory Cache,
20	// and one XICU component.
21	// The peripherals BDEV, CDMA, FBUF, MTTY and the boot BROM
22	// are in the cluster containing address 0xBFC00000.
23	// - The bdev_irq is connected to IRQ_IN[0]
24	// - The cdma_irq is connected to IRQ_IN[1]
25	// - The tty_irq[i] is connected to IRQ_IN[i+2]
26	// For all clusters, the XICU component contains nprocs timers.
27	//
28	// As we target up to 256 clusters, each cluster can contain
29	// at most 16 Mbytes (in a 4Gbytes address space).
30	// - Each memory cache contains 9 Mbytes.
31	// - The Frame buffer contains 2 Mbytes.
32	// - The Boot ROM contains 1 Mbytes.
33	//
34	// General policy for 32 bits address decoding:
35	// To simplifly, all segments base addresses are aligned
36	// on 1 Mbyte addresses. Therefore the 12 address MSB bits
37	// define the target in the direct address space.
38	// In these 12 bits, the (x_width + y_width) MSB bits define
39	// the cluster index, and the 4 LSB bits define the local index:
40	//
41	// \| X_ID \| Y_ID \|---\| L_ID \| OFFSET \|
42	// \|x_width\|y_width\|---\| 4 \| 20 \|
