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

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

1796	  This random key is itself encrypted using a key which is derived
1797	  from SoC's non-volatile secret key and a 16 bit Key identifier.
1798	  The resulting encrypted key along with encrypted data is called a
