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

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

58	  output indicating that autoboot is in progress.
59
60	  Note that this define is used as the (only) argument to a

78	  or the environment variable "bootdelaykey" is specified
79	  and this string is received from console input before
80	  autoboot starts booting, U-Boot gives a command prompt. The

91	  variable "bootstopkey" is specified and this string is

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