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 [31mCONFIG_FSI_MASTER_GPIO[0m tristate "GPIO-based FSI master" depends on [31mCONFIG_GPIOLIB[0m select [31mCONFIG_CRC4[0m ---help--- This option enables a [31mCONFIG_FSI[0m master driver using GPIO lines. config [31mCONFIG_FSI_MASTER_HUB[0m tristate "FSI hub master" ---help--- This option enables a [31mCONFIG_FSI[0m hub master driver. Hub is a type of [31mCONFIG_FSI[0m master that is connected to the upstream master via a slave. Hubs allow chaining of [31mCONFIG_FSI[0m links to an arbitrary depth. This allows for a high target device fanout. config [31mCONFIG_FSI_MASTER_AST_CF[0m tristate "FSI master based on Aspeed ColdFire coprocessor" depends on [31mCONFIG_GPIOLIB[0m depends on [31mCONFIG_GPIO_ASPEED[0m select [31mCONFIG_GENERIC_ALLOCATOR[0m ---help--- This option enables a [31mCONFIG_FSI[0m 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 [31mCONFIG_FSI_SCOM[0m tristate "SCOM FSI client device driver" ---help--- This option enables an [31mCONFIG_FSI[0m based SCOM device driver. config [31mCONFIG_FSI_SBEFIFO[0m tristate "SBEFIFO FSI client device driver" depends on [31mCONFIG_OF_ADDRESS[0m ---help--- This option enables an [31mCONFIG_FSI[0m based SBEFIFO device driver. The SBEFIFO is a pipe-like [31mCONFIG_FSI[0m device for communicating with the self boot engine (SBE) on POWER processors. config [31mCONFIG_FSI_OCC[0m tristate "OCC SBEFIFO client device driver" depends on [31mCONFIG_FSI_SBEFIFO[0m ---help--- This option enables an SBEFIFO based On-Chip Controller (OCC) device driver. The OCC is a device embedded on a POWER processor that collects and aggregates sensor data from the processor and system. The OCC can provide the raw sensor data as well as perform thermal and power management on the system. endif |
