6 | help | |
7 | Enable U-Boot's command-line functions. This provides a means | |
8 | to enter commands into U-Boot for a wide variety of purposes. It | |
9 | also allows scripts (containing commands) to be executed. | |
10 | Various commands and command categorys can be indivdually enabled. | |
11 | Depending on the number of commands enabled, this can add | |
12 | substantially to the size of U-Boot. | |

17 | help |
18 | This option enables the "hush" shell (from Busybox) as command line | |
19 | interpreter, thus enabling powerful command line syntax like | |
20 | if...then...else...fi conditionals or `&&' and '||' | |
21 | constructs ("shell scripts"). | |

23 | If disabled, you get the old, much simpler behaviour with a somewhat | |

710 | help | |
711 | Provides an 'iotrace' command which supports recording I/O reads and | |
712 | writes in a trace buffer in memory . It also maintains a checksum | |
713 | of the trace records (even if space is exhausted) so that the | |
714 | sequence of I/O accesses can be verified. | |
715 | ||
716 | When debugging drivers it is useful to see what I/O accesses were | |
717 | done and in what order. | |
718 | ||
719 | Even if the individual accesses are of little interest it can be | |
720 | useful to verify that the access pattern is consistent each time | |
721 | an operation is performed. In this case a checksum can be used to | |
722 | characterise the operation of a driver. The checksum can be compared | |
723 | across different runs of the operation to verify that the driver is | |
724 | working properly. | |
725 | ||
726 | In particular, when performing major refactoring of the driver, where | |
727 | the access pattern should not change, the checksum provides assurance | |
728 | that the refactoring work has not broken the driver. | |
729 | ||
730 | This works by sneaking into the io.h heder for an architecture and | |
731 | redirecting I/O accesses through iotrace's tracing mechanism. | |
732 | ||
733 | For now no commands are provided to examine the trace buffer. The | |
734 | format is fairly simple, so 'md' is a reasonable substitute. | |
735 | ||
736 | Note: The checksum feature is only useful for I/O regions where the | |
737 | contents do not change outside of software control. Where this is not | |
738 | suitable you can fall back to manually comparing the addresses. It | |
739 | might be useful to enhance tracing to only checksum the accesses and | |
740 | not the data read/written. | |
