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

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

87	help
88	  This option enables stopping (aborting) of the automatic
89	  boot feature only by issuing a specific input key or
90	  string. If CONFIG_AUTOBOOT_STOP_STR or the environment
91	  variable "bootstopkey" is specified and this string is
92	  received from console input before autoboot starts booting,
93	  U-Boot gives a command prompt. The U-Boot prompt never

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

715
716config CMD_IOTRACE
717	bool "iotrace - Support for tracing I/O activity"
718	help
719	  Provides an 'iotrace' command which supports recording I/O reads and
720	  writes in a trace buffer in memory . It also maintains a checksum
721	  of the trace records (even if space is exhausted) so that the
722	  sequence of I/O accesses can be verified.
723
724	  When debugging drivers it is useful to see what I/O accesses were
725	  done and in what order.
726
727	  Even if the individual accesses are of little interest it can be
728	  useful to verify that the access pattern is consistent each time
729	  an operation is performed. In this case a checksum can be used to
730	  characterise the operation of a driver. The checksum can be compared
731	  across different runs of the operation to verify that the driver is
732	  working properly.
733
734	  In particular, when performing major refactoring of the driver, where
735	  the access pattern should not change, the checksum provides assurance
736	  that the refactoring work has not broken the driver.
737
738	  This works by sneaking into the io.h heder for an architecture and
739	  redirecting I/O accesses through iotrace's tracing mechanism.
740
741	  For now no commands are provided to examine the trace buffer. The
742	  format is fairly simple, so 'md' is a reasonable substitute.
743
744	  Note: The checksum feature is only useful for I/O regions where the
745	  contents do not change outside of software control. Where this is not
746	  suitable you can fall back to manually comparing the addresses. It
747	  might be useful to enhance tracing to only checksum the accesses and
748	  not the data read/written.
