  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"

  881. Provides an 'iotrace' command which supports recording I/O reads and
  882. writes in a trace buffer in memory . It also maintains a checksum
  883. of the trace records (even if space is exhausted) so that the
  884. sequence of I/O accesses can be verified.
  885. When debugging drivers it is useful to see what I/O accesses were
  886. done and in what order.
  887. Even if the individual accesses are of little interest it can be
  888. useful to verify that the access pattern is consistent each time
  889. an operation is performed. In this case a checksum can be used to
  890. characterise the operation of a driver. The checksum can be compared
  891. across different runs of the operation to verify that the driver is
  892. working properly.
  893. In particular, when performing major refactoring of the driver, where
  894. the access pattern should not change, the checksum provides assurance
  895. that the refactoring work has not broken the driver.
  896. This works by sneaking into the io.h heder for an architecture and
  897. redirecting I/O accesses through iotrace's tracing mechanism.
  898. For now no commands are provided to examine the trace buffer. The
  899. format is fairly simple, so 'md' is a reasonable substitute.
  900. Note: The checksum feature is only useful for I/O regions where the
  901. contents do not change outside of software control. Where this is not
  902. suitable you can fall back to manually comparing the addresses. It
  903. might be useful to enhance tracing to only checksum the accesses and
  904. not the data read/written.
