FSI - the FRU Support Interface - is a simple bus for low-level

---help---
|

|
|
This option causes char devices created for FSI devices to be
|
||
|
|
located under a common /dev/fsi/ directory. Set to N unless your
|
||
|
|
userspace has been updated to handle the new location.
|
||
|
|
|
||
|
|
Additionally, it also causes the char device names to be offset
|
||
|
|
by one so that chip 0 will have /dev/scom1 and chip1 /dev/scom2
|
||
|
|
to match old userspace expectations.
|
||
|
|
|
||
|
|
New userspace will use udev rules to generate predictable access
|

|
|
symlinks in /dev/fsi/by-path when this option is enabled.

This option enables a FSI hub master driver. Hub is a type of FSI
|

|
master that is connected to the upstream master via a slave. Hubs

allow chaining of FSI links to an arbitrary depth. This allows for

a high target device fanout.
