drochner 34c0afbf8d implement a check whether a BAR is present at all at a given configuration
space address and use it where the mappings of the VGA card are registered
before descenting too deep into "memory" type specific code
(pci_mem_find() gets noisy if it doesn't like the register)

bouyer ec89a92254 When testing for a void region, use PCI_MAPREG_MEM_SIZE() for 32bit memaddr.
If the 32bit mask read is 0, wmask will be 0xffffffff00000000, and
PCI_MAPREG_MEM64_SIZE() won't make this 0.

thorpej 0b82c9610f Don't check for a BAR address past PCI_MAPREG_END; some devices
have BARs way out in left field.

thorpej 5939e70ca3 Add support for mapping 64-bit PCI memory space. If the region
is mapped in a way that is inaccessible by a 32-bit bus_addr_t, then
print a message to that effect and return failure.

Original patches by Bill Studenmund, with a few small changes by me.

drochner 4f1e715248 use BUS_SPACE_MAP_PREFETCHABLE instead BUS_SPACE_MAP_CACHEABLE where the
PCI BAR bit is referred to

thorpej 8eb7170ff8 Back out last change. (Partially my fault, for not reviewing it close
enough.)

lonhyn a9ad6cae19 pci_mapreg_info() has been changed to take arguments like pci_mapreg_map() 1997-10-03 18:45:39 +00:00
mycroft 3e5cee3ce5 If the region size turns out to be 0, return an error. This is what will
happen if we try to use a mapping register that's not actually defined.

mycroft 5da739c6b8 * Rewrite pci_io_find() and pci_mem_find() using my original pci_map_io() and
pci_map_mem(), with appropriate changes for bus_space.
* Add extra arguments for use by pci_mapreg_*(), and make the functions
static.
* Rewrite pci_mapreg_info() and pci_mapreg_map() as wrappers around
pci_*_find(), using the documented interface.
