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 <asm/byteorder.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. + */ + +#define CMA_MB_RAM_BASE (CFG_CMA_MB_BASE+0x0000000) +#define CMA_MB_RAM_SIZE 0x2000000 /* dip sws set actual size */
