31 * pci_map_physmem() - map a PCI device into memory
33 * This is used on sandbox to map a device into memory so that it can be
34 * used with normal memory access. After this call, some part of the device's
35 * internal structure becomes visible.
37 * This function is normally called from sandbox's map_sysmem() automatically.
39 * @paddr: Physical memory address, normally corresponding to a PCI BAR
40 * @lenp: On entry, the size of the area to map, On exit it is updated
41 * to the size actually mapped, which may be less if the device
43 * @devp: Returns the device which mapped into this space
44 * @ptrp: Returns a pointer to the mapped address. The device's space
45 * can be accessed as @lenp bytes starting here
46 * @return 0 if OK, -ve on error

52 * pci_unmap_physmem() - undo a memory mapping
54 * This must be called after pci_map_physmem() to undo the mapping.
56 * @paddr: Physical memory address, as passed to pci_map_physmem()
57 * @len: Size of area mapped, as returned by pci_map_physmem()
58 * @dev: Device to unmap, as returned by pci_map_physmem()

65 * sandbox_set_enable_pci_map() - Enable / disable PCI address mapping
67 * Since address mapping involves calling every driver, provide a way to
68 * enable and disable this. It can be handled automatically by the emulator
69 * uclass, which knows if any emulators are currently active.
71 * If this is disabled, pci_map_physmem() will not be called from
