Revision f2818f22

IDf2818f22016b072388363dd56c0c8cd5dfb936bb

Added by Artyom Tarasenko about 13 years ago

esp: handle "select without attention"

Up to now "select without attention" was handled the same way as
"select with attention". According to

http://www.ibiblio.org/pub/historic-linux/early-ports/Sparc/NCR/NCR53C9X.txt

select without ATN sends the CDB (Command Descriptor Block) directly,
whereas select with ATN sends one message phase byte
followed by 6, 10, or 12 command phase bytes.

The attached patch implements the behaviour described above.
