41 * diagram illustrating the role of the configuration
42 * constants
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).
