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

532
533config CMD_IOTRACE
534	bool "iotrace - Support for tracing I/O activity"
535	help
536	  Provides an 'iotrace' command which supports recording I/O reads and
537	  writes in a trace buffer in memory . It also maintains a checksum
538	  of the trace records (even if space is exhausted) so that the
539	  sequence of I/O accesses can be verified.
540
541	  When debugging drivers it is useful to see what I/O accesses were
542	  done and in what order.
543
544	  Even if the individual accesses are of little interest it can be
545	  useful to verify that the access pattern is consistent each time
546	  an operation is performed. In this case a checksum can be used to
547	  characterise the operation of a driver. The checksum can be compared
548	  across different runs of the operation to verify that the driver is
549	  working properly.
550
551	  In particular, when performing major refactoring of the driver, where
552	  the access pattern should not change, the checksum provides assurance
553	  that the refactoring work has not broken the driver.
554
555	  This works by sneaking into the io.h heder for an architecture and
556	  redirecting I/O accesses through iotrace's tracing mechanism.
557
558	  For now no commands are provided to examine the trace buffer. The
559	  format is fairly simple, so 'md' is a reasonable substitute.
560
561	  Note: The checksum feature is only useful for I/O regions where the
562	  contents do not change outside of software control. Where this is not
563	  suitable you can fall back to manually comparing the addresses. It
564	  might be useful to enhance tracing to only checksum the accesses and
565	  not the data read/written.
