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 '||' | |

201 | module, if U-Boot is chain-loaded from something else. ACPI tables | |
202 | can also include code, to perform hardware-specific tasks required | |

1044 | to write values to the I/O space. This can be useful for manually | |
1045 | checking the state of devices during boot when debugging device | |

1048 | config CMD_IOTRACE |
1049 | bool "iotrace - Support for tracing I/O activity" | |
1050 | help | |
1051 | Provides an 'iotrace' command which supports recording I/O reads and | |
1052 | writes in a trace buffer in memory . It also maintains a checksum | |
1053 | of the trace records (even if space is exhausted) so that the | |
1054 | sequence of I/O accesses can be verified. | |
1055 | ||
1056 | When debugging drivers it is useful to see what I/O accesses were | |
1057 | done and in what order. | |
1058 | ||
1059 | Even if the individual accesses are of little interest it can be | |
1060 | useful to verify that the access pattern is consistent each time | |
1061 | an operation is performed. In this case a checksum can be used to | |
1062 | characterise the operation of a driver. The checksum can be compared | |
1063 | across different runs of the operation to verify that the driver is | |
1064 | working properly. | |
1065 | ||
1066 | In particular, when performing major refactoring of the driver, where | |
1067 | the access pattern should not change, the checksum provides assurance | |
1068 | that the refactoring work has not broken the driver. | |
1069 | ||
1070 | This works by sneaking into the io.h heder for an architecture and | |
1071 | redirecting I/O accesses through iotrace's tracing mechanism. | |
1072 | ||
1073 | For now no commands are provided to examine the trace buffer. The | |
1074 | format is fairly simple, so 'md' is a reasonable substitute. | |
1075 | ||
1076 | Note: The checksum feature is only useful for I/O regions where the | |
1077 | contents do not change outside of software control. Where this is not | |
1078 | suitable you can fall back to manually comparing the addresses. It | |
1079 | might be useful to enhance tracing to only checksum the accesses and | |
1080 | not the data read/written. | |
