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