43 | * PCI_MEM_WIN0: CPU starting addr where PCI memory space is visible |
---|
44 | * PCI_MEM_BASE: CPU address of PCI mem addr. zero. (regardless of this |
---|
45 | * address being 'visible' or not!). |
---|
46 | * _VME_A32_WIN0_ON_PCI: PCI starting addr of the 1st window to VME |
---|
47 | * _VME_A32_WIN0_ON_VME: VME address of that same window |
---|
48 | * |
---|
49 | * AFAIK, only PreP boards have a non-zero PCI_MEM_BASE (i.e., an offset between |
---|
50 | * CPU and PCI addresses). The mvme2300 'ppcbug' firmware configures the PCI |
---|
51 | * bus using PCI base addresses! I.e., drivers need to add PCI_MEM_BASE to |
---|
52 | * the base address read from PCI config.space in order to translate that |
---|
53 | * into a CPU address. |
---|
54 | * |
---|
55 | * NOTE: VME addresses should NEVER be translated using these constants! |
---|
56 | * they are strictly for BSP internal use. Drivers etc. should use |
---|
57 | * the translation routines int VME.h (BSP_vme2local_adrs/BSP_local2vme_adrs). |
