10 The AHA-1542 is a bus-master device, and your patch makes the driver give the
16 so-called "bus address".

21  - CPU untranslated.  This is the "physical" address.  Physical address 
24  - CPU translated address. This is the "virtual" address, and is 
28  - bus address. This is the address of memory as seen by OTHER devices, 
30    addresses, with each device seeing memory in some device-specific way, but
36 address, and things are very simple indeed. However, they are that simple

44 	2 GB-3 GB	"system IO" (inb/out and similar accesses on x86)
45 	3 GB-4 GB 	"IO memory" (shared memory over the IO bus)

153  - remapping and writing:
155 	 * remap framebuffer PCI memory area at 0xFC000000,
157 	 * access only the 640k-1MB area, so anything else
168  - copying and clearing:
