  8. ---help---
  9. FSI - the FRU Support Interface - is a simple bus for low-level
  10. access to POWER-based hardware.
  11. if FSI
  12. config FSI_NEW_DEV_NODE
  13. bool "Create '/dev/fsi' directory for char devices"
  14. default n
  15. ---help---
  16. This option causes char devices created for FSI devices to be
  17. located under a common /dev/fsi/ directory. Set to N unless your
  18. userspace has been updated to handle the new location.
  19. Additionally, it also causes the char device names to be offset
  20. by one so that chip 0 will have /dev/scom1 and chip1 /dev/scom2
  21. to match old userspace expectations.
  22. New userspace will use udev rules to generate predictable access
  23. symlinks in /dev/fsi/by-path when this option is enabled.
  24. config FSI_MASTER_GPIO
  25. tristate "GPIO-based FSI master"
  26. depends on GPIOLIB
  27. select CRC4
  28. ---help---
  29. This option enables a FSI master driver using GPIO lines.
  30. config FSI_MASTER_HUB
  31. tristate "FSI hub master"
  32. ---help---
  33. This option enables a FSI hub master driver. Hub is a type of FSI
  34. master that is connected to the upstream master via a slave. Hubs
  35. allow chaining of FSI links to an arbitrary depth. This allows for
  36. a high target device fanout.
  37. config FSI_MASTER_AST_CF
  38. tristate "FSI master based on Aspeed ColdFire coprocessor"
  39. depends on GPIOLIB
  40. depends on GPIO_ASPEED
  41. select GENERIC_ALLOCATOR
  42. ---help---
  43. This option enables a FSI master using the AST2400 and AST2500 GPIO
  44. lines driven by the internal ColdFire coprocessor. This requires
  45. the corresponding machine specific ColdFire firmware to be available.
  46. config FSI_SCOM
  47. tristate "SCOM FSI client device driver"
  48. ---help---
  49. This option enables an FSI based SCOM device driver.
  50. config FSI_SBEFIFO
  51. tristate "SBEFIFO FSI client device driver"
  52. depends on OF_ADDRESS
  53. ---help---
  54. This option enables an FSI based SBEFIFO device driver. The SBEFIFO is
  55. a pipe-like FSI device for communicating with the self boot engine
  56. (SBE) on POWER processors.
