+ tristate "FSI support"
+ depends on OF
+ select CRC4
+ ---help---
+ FSI - the FRU Support Interface - is a simple bus for low-level
+ access to POWER-based hardware.
+
+if FSI
+
+config FSI_NEW_DEV_NODE
+ bool "Create '/dev/fsi' directory for char devices"
+ default n
+ ---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.
+
+config FSI_MASTER_GPIO
+ tristate "GPIO-based FSI master"
+ depends on GPIOLIB
+ select CRC4
+ ---help---
+ 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_MASTER_AST_CF
+ tristate "FSI master based on Aspeed ColdFire coprocessor"
+ depends on GPIOLIB
+ depends on GPIO_ASPEED
+ select GENERIC_ALLOCATOR
+ ---help---
+ This option enables a FSI master using the AST2400 and AST2500 GPIO
+ lines driven by the internal ColdFire coprocessor. This requires
+ the corresponding machine specific ColdFire firmware to be available.
+
+config FSI_SCOM
+ tristate "SCOM FSI client device driver"
+ ---help---
+ This option enables an FSI based SCOM device driver.
+
+config FSI_SBEFIFO
+ tristate "SBEFIFO FSI client device driver"
+ depends on OF_ADDRESS
+ ---help---
+ This option enables an FSI based SBEFIFO device driver. The SBEFIFO is
+ a pipe-like FSI device for communicating with the self boot engine
+ (SBE) on POWER processors.
