*
|

* On Sparc32 this is the serial port, mouse and keyboard part of chip STP2001
|

* (Slave I/O), also produced as NCR89C105. See

||||
* http://www.ibiblio.org/pub/historic-linux/early-ports/Sparc/NCR/NCR89C105.txt
|
||||
*
|
||||
* The serial ports implement full AMD AM8530 or Zilog Z8530 chips,
|
||||
* mouse and keyboard ports don't implement all functions and they are
|
||||
* only asynchronous. There is no DMA.
|
||||
*
|
||||
* Z85C30 is also used on PowerMacs. There are some small differences
|
||||
* between Sparc version (sunzilog) and PowerMac (pmac):
|
||||
* Offset between control and data registers
|
||||
* There is some kind of lockup bug, but we can ignore it
|
||||
* CTS is inverted
|
||||
* DMA on pmac using DBDMA chip
|
||||
* pmac can do IRDA and faster rates, sunzilog can only do 38400
|
||||
* pmac baud rate generator clock is 3.6864 MHz, sunzilog 4.9152 MHz
