|
|
* - PCI config registers are always accessible through PCI config space
|
|
* - Full 512K space mapped into memory using PCI memory mapped access
|
|
* - 256-byte I/O space mapped through PCI I/O access
|
|
* - Full 512K space mapped through indirect I/O using PCI I/O access
|
|
* It's possible to use either memory mapped mode or I/O mode to access
|
|
* the registers, but memory mapped is usually the easiest. All registers
|
|
* are 32 bits wide and must be accessed using 32-bit operations.
