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.

674 bool "iotrace - Support for tracing I/O activity"
675 help
676 Provides an 'iotrace' command which supports recording I/O reads and
677 writes in a trace buffer in memory . It also maintains a checksum
678 of the trace records (even if space is exhausted) so that the
679 sequence of I/O accesses can be verified.
680
681 When debugging drivers it is useful to see what I/O accesses were
682 done and in what order.
683
684 Even if the individual accesses are of little interest it can be
685 useful to verify that the access pattern is consistent each time
686 an operation is performed. In this case a checksum can be used to
687 characterise the operation of a driver. The checksum can be compared
688 across different runs of the operation to verify that the driver is
689 working properly.
690
691 In particular, when performing major refactoring of the driver, where
692 the access pattern should not change, the checksum provides assurance
693 that the refactoring work has not broken the driver.
694
695 This works by sneaking into the io.h heder for an architecture and
696 redirecting I/O accesses through iotrace's tracing mechanism.
697
698 For now no commands are provided to examine the trace buffer. The
699 format is fairly simple, so 'md' is a reasonable substitute.
700
701 Note: The checksum feature is only useful for I/O regions where the
702 contents do not change outside of software control. Where this is not
703 suitable you can fall back to manually comparing the addresses. It
704 might be useful to enhance tracing to only checksum the accesses and
705 not the data read/written.

1166 Freescale's SEC block has built-in Blob Protocol which provides
1167 a method for protecting user-defined data across system power
1168 cycles. SEC block protects data in a data structure called a Blob,
1169 which provides both confidentiality and integrity protection.

1174 This random key is itself encrypted using a key which is derived
1175 from SoC's non-volatile secret key and a 16 bit Key identifier.
1176 The resulting encrypted key along with encrypted data is called a
1177 blob. The non-volatile secure key is available for use only during
