  1. menu "Command line interface"
  2. config CMDLINE
  3. bool "Support U-Boot commands"
  4. default y
  5. help
  6. Enable U-Boot's command-line functions. This provides a means
  7. to enter commands into U-Boot for a wide variety of purposes. It
  8. also allows scripts (containing commands) to be executed.
  9. Various commands and command categorys can be indivdually enabled.
  10. Depending on the number of commands enabled, this can add
  11. substantially to the size of U-Boot.
  12. config HUSH_PARSER
  13. bool "Use hush shell"
  14. depends on CMDLINE
  15. help
  16. This option enables the "hush" shell (from Busybox) as command line
  17. interpreter, thus enabling powerful command line syntax like
  18. if...then...else...fi conditionals or `&&' and '||'
  19. constructs ("shell scripts").
  20. If disabled, you get the old, much simpler behaviour with a somewhat
  21. smaller memory footprint.
  22. config CMDLINE_EDITING
  23. bool "Enable command line editing"
  24. depends on CMDLINE
  25. default y
  26. help
  27. Enable editing and History functions for interactive command line
  28. input operations
  29. config AUTO_COMPLETE
  30. bool "Enable auto complete using TAB"
  31. depends on CMDLINE
  32. default y
  33. help
  34. Enable auto completion of commands using TAB.
  35. config SYS_LONGHELP
  36. bool "Enable long help messages"
  37. depends on CMDLINE
  38. default y if CMDLINE
  39. help
  40. Defined when you want long help messages included
  41. Do not set this option when short of memory.
  42. config SYS_PROMPT
  43. string "Shell prompt"
  44. default "Zynq> " if ARCH_ZYNQ
  45. default "ZynqMP> " if ARCH_ZYNQMP
  46. default "=> "
  47. help
  48. This string is displayed in the command line to the left of the
  49. cursor.
  50. config SYS_XTRACE
  51. string "Command execution tracer"
  52. depends on CMDLINE
  53. default y if CMDLINE
  54. help
  55. This option enables the possiblity to print all commands before
  56. executing them and after all variables are evaluated (similar
  57. to Bash's xtrace/'set -x' feature).
  58. To enable the tracer a variable "xtrace" needs to be defined in
  59. the environment.

  818. writes in a trace buffer in memory . It also maintains a checksum
  819. of the trace records (even if space is exhausted) so that the
  820. sequence of I/O accesses can be verified.
  821. When debugging drivers it is useful to see what I/O accesses were
  822. done and in what order.
  823. Even if the individual accesses are of little interest it can be
  824. useful to verify that the access pattern is consistent each time
  825. an operation is performed. In this case a checksum can be used to
  826. characterise the operation of a driver. The checksum can be compared
  827. across different runs of the operation to verify that the driver is
  828. working properly.
  829. In particular, when performing major refactoring of the driver, where
  830. the access pattern should not change, the checksum provides assurance
  831. that the refactoring work has not broken the driver.
  832. This works by sneaking into the io.h heder for an architecture and
  833. redirecting I/O accesses through iotrace's tracing mechanism.
  834. For now no commands are provided to examine the trace buffer. The
  835. format is fairly simple, so 'md' is a reasonable substitute.
  836. Note: The checksum feature is only useful for I/O regions where the
  837. contents do not change outside of software control. Where this is not
  838. suitable you can fall back to manually comparing the addresses. It
  839. might be useful to enhance tracing to only checksum the accesses and
  840. not the data read/written.
