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

68	  This option enables stopping (aborting) of the automatic
69	  boot feature only by issuing a specific input key or

114	  variable "bootstopkey" is specified and this string is

124	  This option allows for the boot sequence to be interrupted
125	  by ctrl-c, in addition to the "bootdelaykey" and "bootstopkey".

791config CMD_IOTRACE

794	  Provides an 'iotrace' command which supports recording I/O reads and
795	  writes in a trace buffer in memory . It also maintains a checksum
796	  of the trace records (even if space is exhausted) so that the
797	  sequence of I/O accesses can be verified.
798
799	  When debugging drivers it is useful to see what I/O accesses were
800	  done and in what order.
801
802	  Even if the individual accesses are of little interest it can be
803	  useful to verify that the access pattern is consistent each time
804	  an operation is performed. In this case a checksum can be used to
805	  characterise the operation of a driver. The checksum can be compared
806	  across different runs of the operation to verify that the driver is
807	  working properly.
808
809	  In particular, when performing major refactoring of the driver, where
810	  the access pattern should not change, the checksum provides assurance
811	  that the refactoring work has not broken the driver.
812
813	  This works by sneaking into the io.h heder for an architecture and
814	  redirecting I/O accesses through iotrace's tracing mechanism.
815
816	  For now no commands are provided to examine the trace buffer. The
817	  format is fairly simple, so 'md' is a reasonable substitute.
818
819	  Note: The checksum feature is only useful for I/O regions where the
820	  contents do not change outside of software control. Where this is not
821	  suitable you can fall back to manually comparing the addresses. It
822	  might be useful to enhance tracing to only checksum the accesses and
823	  not the data read/written.
