   38  * Registers for the Adaptec AIC-6915 Starfire. The Starfire has a 512K
   39  * register space. These registers can be accessed in the following way:
   40  * - PCI config registers are always accessible through PCI config space
   41  * - Full 512K space mapped into memory using PCI memory mapped access
   42  * - 256-byte I/O space mapped through PCI I/O access
   43  * - Full 512K space mapped through indirect I/O using PCI I/O access
   44  * It's possible to use either memory mapped mode or I/O mode to access
   45  * the registers, but memory mapped is usually the easiest. All registers
   46  * are 32 bits wide and must be accessed using 32-bit operations.
