16 * Cogent Motherboard Address Map
18 * The size of a Cogent motherboard address space is 256 Mbytes (i.e. 28 bits).
20 * The first 32 Mbyte (0x0000000-0x1FFFFFF) is usually RAM. The following
21 * 3 x 32 Mbyte areas (0x2000000-0x3FFFFFF, 0x4000000-0x5FFFFFF and
22 * 0x6000000-0x7FFFFFF) are general I/O "slots" (slots 1, 2 and 3).
23 * Most other motherboard devices have registers mapped into the area
24 * 0xE000000-0xFFFFFFF (Motherboard I/O slot?). The area 0x8000000-0xDFFFFFF
25 * is free for whatever.
27 * The location of the motherboard address space in the physical address space
28 * of the cpu is given by CMA_MB_BASE. This value is determined by the cpu
29 * module plugged into the motherboard and is configured above.
31 * Motherboard I/O devices mapped into the area (0xE000000-0xFFFFFFF)
32 * generally only use byte lane 0 (D0-7) for their transfers, i.e. only
33 * 8 bit, or 1 byte, transfers can take place, so all the registers are
34 * only 8 bits wide. The exceptions are the motherboard flash, which uses
35 * byte lanes 0 and 1 (i.e. 16 bits), and the mapped PCI address space.
37 * I/O registers within the mapped motherboard devices are 64 bit aligned
38 * i.e. they are 8 bytes apart. For big endian addressing, the 8 bit register
39 * will be at byte 7 (the address + 7). For little endian addressing, the
40 * register will be at byte 0 (the address + 0). To learn the endianess
41 * we must include <endian.h>
43 * Take the CMA102 and CMA111 motherboards as examples...
45 * The CMA102 has three CMABus I/O Expansion slots and no PCI bridge. The 3
46 * CMABus slots are each mapped directly onto the three general I/O slots.
48 * The CMA111 has only one CMABus I/O Expansion slot, but has a V360EPC PCI
49 * bridge. The CMABus slot is mapped onto general I/O slot 1. The standard
50 * PCI Bus space is mapped onto general I/O slot 2, with a small area at the
51 * top reserved for access to the V360EPC registers (0x5FF0000-0x5FFFFFF).
52 * I/O slot 3 is unused. The extended PCI Bus space is mapped onto the area
53 * 0xA000000-0xDFFFFFF.
