Hi Steve,
Your clarification and a second look at the implementation note (PCI2.1 3.2.2) raises
a question. Is it not possible to map a PCI memory device into the bottom memory
space as in this case all range bits will be zero ? How should the device driver
distinguish between a genuine address space (let us say 16 MB located at bottom most
part) from a non-allocated memory space ?
Thanks,
Tripathi.
