thorpej a51a1d8cdd - Get rid of the prot bits in the mem_clusters[] array when 
reserving RAM in the bus_mem extent map.  Problem pointed
  out by Artur Grabowski.
- Work around a slightly annoying bit of behavior exhibited by
  the UP1000 firmware.  The UP1000 firmware reports the space
  consumed by the "ISA hole" in the same MDDT entry as two
  chunks of RAM (on either side of the hole) used by the PALcode,
  all as one "reserved for PALcode" chunk.  We must take this
  into account when reserving RAM in the bus_mem extent map.

thorpej d615083897 The AMD 751 doesn't have DMA windows, so allocate the RAM out of the 
PCI memory extent map.  Bad things will happen if we try to assign
a device where RAM is mapped into PCI space.

thorpej 69a6fe113c Garbage-collect CHIP_PHYSADDR(). 2000-06-26 19:46:24 +00:00
thorpej 9a2d9ff68b Because of the Cool sign-extension hack we use to access PCI space, 
the `get window' method ends up with the wrong physical address to
pass onto userspace (which wants to mmap the space).

Compensate by adding a CHIP_PHYSADDR() macro which un-hacks the address
suitably for mapping with other-than-KSEG.
