Subject: [PATCH] ieee1275: set-address bus specific method
|
|
|
|
IEEE 1275-1994 Standard for Boot (Initialization Configuration)
|
|
Firmware: Core Requirements and Practices
|
|
E.3.2.2 Bus-specific methods for bus nodes
|
|
|
|
A package implementing the scsi-2 device type shall implement the
|
|
following bus-specific method:
|
|
|
|
set-address ( unit# target# -- )
|
|
Sets the SCSI target number (0x0..0xf) and unit number (0..7) to which
|
|
subsequent commands apply.
|
|
|
|
This function is for devices with #address-cells == 2
