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

20	  if...then...else...fi conditionals or `&&' and '||'

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

81	  output indicating that autoboot is in progress.
82
83	  Note that this define is used as the (only) argument to a

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

113	  string. If CONFIG_AUTOBOOT_STOP_STR or the environment
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".

780config CMD_IOTRACE

782	help
783	  Provides an 'iotrace' command which supports recording I/O reads and
784	  writes in a trace buffer in memory . It also maintains a checksum
785	  of the trace records (even if space is exhausted) so that the
786	  sequence of I/O accesses can be verified.
787
788	  When debugging drivers it is useful to see what I/O accesses were
789	  done and in what order.
790
791	  Even if the individual accesses are of little interest it can be
792	  useful to verify that the access pattern is consistent each time
793	  an operation is performed. In this case a checksum can be used to
794	  characterise the operation of a driver. The checksum can be compared
795	  across different runs of the operation to verify that the driver is
796	  working properly.
797
798	  In particular, when performing major refactoring of the driver, where
799	  the access pattern should not change, the checksum provides assurance
800	  that the refactoring work has not broken the driver.
801
802	  This works by sneaking into the io.h heder for an architecture and
803	  redirecting I/O accesses through iotrace's tracing mechanism.
804
805	  For now no commands are provided to examine the trace buffer. The
806	  format is fairly simple, so 'md' is a reasonable substitute.
807
808	  Note: The checksum feature is only useful for I/O regions where the
809	  contents do not change outside of software control. Where this is not
810	  suitable you can fall back to manually comparing the addresses. It
811	  might be useful to enhance tracing to only checksum the accesses and
812	  not the data read/written.
