6	help
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.

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

57	  CONFIG_BOOTDELAY starts. If it is not defined	there is no
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

514
515config CMD_IOTRACE
516	bool "iotrace - Support for tracing I/O activity"
517	help
518	  Provides an 'iotrace' command which supports recording I/O reads and
519	  writes in a trace buffer in memory . It also maintains a checksum
520	  of the trace records (even if space is exhausted) so that the
521	  sequence of I/O accesses can be verified.
522
523	  When debugging drivers it is useful to see what I/O accesses were
524	  done and in what order.
525
526	  Even if the individual accesses are of little interest it can be
527	  useful to verify that the access pattern is consistent each time
528	  an operation is performed. In this case a checksum can be used to
529	  characterise the operation of a driver. The checksum can be compared
530	  across different runs of the operation to verify that the driver is
531	  working properly.
532
533	  In particular, when performing major refactoring of the driver, where
534	  the access pattern should not change, the checksum provides assurance
535	  that the refactoring work has not broken the driver.
536
537	  This works by sneaking into the io.h heder for an architecture and
538	  redirecting I/O accesses through iotrace's tracing mechanism.
539
540	  For now no commands are provided to examine the trace buffer. The
541	  format is fairly simple, so 'md' is a reasonable substitute.
542
543	  Note: The checksum feature is only useful for I/O regions where the
544	  contents do not change outside of software control. Where this is not
545	  suitable you can fall back to manually comparing the addresses. It
546	  might be useful to enhance tracing to only checksum the accesses and
547	  not the data read/written.
