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.

632 bool "iotrace - Support for tracing I/O activity"
633 help
634 Provides an 'iotrace' command which supports recording I/O reads and
635 writes in a trace buffer in memory . It also maintains a checksum
636 of the trace records (even if space is exhausted) so that the
637 sequence of I/O accesses can be verified.
638
639 When debugging drivers it is useful to see what I/O accesses were
640 done and in what order.
641
642 Even if the individual accesses are of little interest it can be
643 useful to verify that the access pattern is consistent each time
644 an operation is performed. In this case a checksum can be used to
645 characterise the operation of a driver. The checksum can be compared
646 across different runs of the operation to verify that the driver is
647 working properly.
648
649 In particular, when performing major refactoring of the driver, where
650 the access pattern should not change, the checksum provides assurance
651 that the refactoring work has not broken the driver.
652
653 This works by sneaking into the io.h heder for an architecture and
654 redirecting I/O accesses through iotrace's tracing mechanism.
655
656 For now no commands are provided to examine the trace buffer. The
657 format is fairly simple, so 'md' is a reasonable substitute.
658
659 Note: The checksum feature is only useful for I/O regions where the
660 contents do not change outside of software control. Where this is not
661 suitable you can fall back to manually comparing the addresses. It
662 might be useful to enhance tracing to only checksum the accesses and
663 not the data read/written.

1097 Encapsulating data as a blob
1098 Each time that the Blob Protocol is used to protect data, a
1099 different randomly generated key is used to encrypt the data.
1100 This random key is itself encrypted using a key which is derived
1101 from SoC's non-volatile secret key and a 16 bit Key identifier.
1102 The resulting encrypted key along with encrypted data is called a
1103 blob. The non-volatile secure key is available for use only during
1104 secure boot.
1105
1106 During decapsulation, the reverse process is performed to get back
1107 the original data.
1108
1109 Sub-commands:
1110 blob enc - encapsulating data as a cryptgraphic blob
1111 blob dec - decapsulating cryptgraphic blob to get the data
1112
1113 Syntax:
1114
1115 blob enc src dst len km
1116
1117 Encapsulate and create blob of data $len bytes long
1118 at address $src and store the result at address $dst.
1119 $km is the 16 byte key modifier is also required for
1120 generation/use as key for cryptographic operation. Key
1121 modifier should be 16 byte long.
1122
1123 blob dec src dst len km
1124
1125 Decapsulate the blob of data at address $src and
1126 store result of $len byte at addr $dst.
1127 $km is the 16 byte key modifier is also required for
1128 generation/use as key for cryptographic operation. Key
1129 modifier should be 16 byte long.
