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.

647 bool "iotrace - Support for tracing I/O activity"
648 help
649 Provides an 'iotrace' command which supports recording I/O reads and
650 writes in a trace buffer in memory . It also maintains a checksum
651 of the trace records (even if space is exhausted) so that the
652 sequence of I/O accesses can be verified.
653
654 When debugging drivers it is useful to see what I/O accesses were
655 done and in what order.
656
657 Even if the individual accesses are of little interest it can be
658 useful to verify that the access pattern is consistent each time
659 an operation is performed. In this case a checksum can be used to
660 characterise the operation of a driver. The checksum can be compared
661 across different runs of the operation to verify that the driver is
662 working properly.
663
664 In particular, when performing major refactoring of the driver, where
665 the access pattern should not change, the checksum provides assurance
666 that the refactoring work has not broken the driver.
667
668 This works by sneaking into the io.h heder for an architecture and
669 redirecting I/O accesses through iotrace's tracing mechanism.
670
671 For now no commands are provided to examine the trace buffer. The
672 format is fairly simple, so 'md' is a reasonable substitute.
673
674 Note: The checksum feature is only useful for I/O regions where the
675 contents do not change outside of software control. Where this is not
676 suitable you can fall back to manually comparing the addresses. It
677 might be useful to enhance tracing to only checksum the accesses and
678 not the data read/written.

1097 This command is based on driver model regulator's API.
1098 User interface features:
1099 - list - list regulator devices
1100 - regulator dev <id> - show or [set] operating regulator device
1101 - regulator info - print constraints info
1102 - regulator status - print operating status
1103 - regulator value <val] <-f> - print/[set] voltage value [uV]
1104 - regulator current <val> - print/[set] current value [uA]
1105 - regulator mode <id> - print/[set] operating mode id
1106 - regulator enable - enable the regulator output
1107 - regulator disable - disable the regulator output
1108
1109 The '-f' (force) option can be used for set the value which exceeds
1110 the limits, which are found in device-tree and are kept in regulator's
1111 uclass platdata structure.

1128 help
1129 This is used with the Freescale secure boot mechanism.
1130
1131 Freescale's SEC block has built-in Blob Protocol which provides
1132 a method for protecting user-defined data across system power
1133 cycles. SEC block protects data in a data structure called a Blob,
1134 which provides both confidentiality and integrity protection.
1135
1136 Encapsulating data as a blob
1137 Each time that the Blob Protocol is used to protect data, a
1138 different randomly generated key is used to encrypt the data.
1139 This random key is itself encrypted using a key which is derived
1140 from SoC's non-volatile secret key and a 16 bit Key identifier.
1141 The resulting encrypted key along with encrypted data is called a
1142 blob. The non-volatile secure key is available for use only during
1143 secure boot.
1144
1145 During decapsulation, the reverse process is performed to get back
1146 the original data.

1148 Sub-commands:
1149 blob enc - encapsulating data as a cryptgraphic blob
