|
* which have no meaning except to get translated by hd64465_isa_port2addr()
|
|
* to an address in the range 0xb0000000-0xb3ffffff. Note that
|
|
* this translation happens to consist of adding the lower 16 bits
|

* of the virtual port number to 0xb0000000. Note also that the manual
|
|
* shows addresses as absolute physical addresses starting at 0x10000000,
|
|
