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

546 Even if the individual accesses are of little interest it can be
547 useful to verify that the access pattern is consistent each time
548 an operation is performed. In this case a checksum can be used to
549 characterise the operation of a driver. The checksum can be compared
550 across different runs of the operation to verify that the driver is
551 working properly.
552
553 In particular, when performing major refactoring of the driver, where
554 the access pattern should not change, the checksum provides assurance
555 that the refactoring work has not broken the driver.
556
557 This works by sneaking into the io.h heder for an architecture and
558 redirecting I/O accesses through iotrace's tracing mechanism.
559
560 For now no commands are provided to examine the trace buffer. The
561 format is fairly simple, so 'md' is a reasonable substitute.
562
563 Note: The checksum feature is only useful for I/O regions where the
564 contents do not change outside of software control. Where this is not
565 suitable you can fall back to manually comparing the addresses. It
566 might be useful to enhance tracing to only checksum the accesses and
567 not the data read/written.

1090 algorithms (such as SHA1, MD5, CRC32). The computed digest can be
1091 saved to memory or to an environment variable. It is also possible
1092 to verify a hash against data in memory.

1114 correctly. The tests cover initialisation, non-volatile RAM, extend,
1115 global lock and checking that timing is within expectations. The
1116 tests pass correctly on Infineon TPMs but may need to be adjusted
1117 for other devices.
