Christopher Bostic 7f9e8f7670 drivers/fsi: Add hub master support
Add an engine driver to expose a "hub" FSI master - which has a set of
control registers in the engine address space, and uses a chunk of the
slave address space for actual FSI communication.

Additional changes from Jeremy Kerr <jk@ozlabs.org>.

FSI - the FRU Support Interface - is a simple bus for low-level
access to POWER-based hardware.

This option enables a FSI master driver using GPIO lines.
config FSI_MASTER_HUB
tristate "FSI hub master"
---help---
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.
config FSI_SCOM
tristate "SCOM FSI client device driver"
---help---
This option enables an FSI based SCOM device driver.
