962 help
963 Provides an 'iotrace' command which supports recording I/O reads and
964 writes in a trace buffer in memory . It also maintains a checksum
965 of the trace records (even if space is exhausted) so that the
966 sequence of I/O accesses can be verified.
967
968 When debugging drivers it is useful to see what I/O accesses were
969 done and in what order.
970
971 Even if the individual accesses are of little interest it can be
972 useful to verify that the access pattern is consistent each time
973 an operation is performed. In this case a checksum can be used to
974 characterise the operation of a driver. The checksum can be compared
975 across different runs of the operation to verify that the driver is
976 working properly.
977
978 In particular, when performing major refactoring of the driver, where
979 the access pattern should not change, the checksum provides assurance
980 that the refactoring work has not broken the driver.
981
982 This works by sneaking into the io.h heder for an architecture and
983 redirecting I/O accesses through iotrace's tracing mechanism.
984
985 For now no commands are provided to examine the trace buffer. The
986 format is fairly simple, so 'md' is a reasonable substitute.
987
988 Note: The checksum feature is only useful for I/O regions where the
989 contents do not change outside of software control. Where this is not
990 suitable you can fall back to manually comparing the addresses. It
991 might be useful to enhance tracing to only checksum the accesses and
992 not the data read/written.

1949 MTD partitioning tool support.
1950 It is strongly encouraged to avoid using this command
1951 anymore along with 'sf', 'nand', 'onenand'. One can still
1952 declare the partitions in the mtdparts environment variable
1953 but better use the MTD stack and the 'mtd' command instead.

1973 This enables the 'spread' sub-command of the mtdparts command.
1974 This command will modify the existing mtdparts variable by increasing
1975 the size of the partitions such that 1) each partition's net size is
1976 at least as large as the size specified in the mtdparts variable and
1977 2) each partition starts on a good block.

2087 UBI is a software layer above MTD layer which admits use of LVM-like
2088 logical volumes on top of MTD devices, hides some complexities of
2089 flash chips like wear and bad blocks and provides some other useful
2090 capabilities. Please, consult the MTD web site for more details
2091 (www.linux-mtd.infradead.org). Activate this option if you want
2092 to use U-Boot UBI commands.
