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 | |

984 | an operation is performed. In this case a checksum can be used to | |
985 | characterise the operation of a driver. The checksum can be compared | |
986 | across different runs of the operation to verify that the driver is | |
987 | working properly. | |
988 | ||
989 | In particular, when performing major refactoring of the driver, where | |
990 | the access pattern should not change, the checksum provides assurance | |
991 | that the refactoring work has not broken the driver. | |
992 | ||
993 | This works by sneaking into the io.h heder for an architecture and | |
994 | redirecting I/O accesses through iotrace's tracing mechanism. | |
995 | ||
996 | For now no commands are provided to examine the trace buffer. The | |
997 | format is fairly simple, so 'md' is a reasonable substitute. | |
998 | ||
999 | Note: The checksum feature is only useful for I/O regions where the | |
1000 | contents do not change outside of software control. Where this is not | |
1001 | suitable you can fall back to manually comparing the addresses. It | |
1002 | might be useful to enhance tracing to only checksum the accesses and | |
1003 | not the data read/written. | |
