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

90	  string. If CONFIG_AUTOBOOT_STOP_STR or the environment
91	  variable "bootstopkey" is specified and this string is

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

698	  Provides an 'iotrace' command which supports recording I/O reads and
699	  writes in a trace buffer in memory . It also maintains a checksum
700	  of the trace records (even if space is exhausted) so that the
701	  sequence of I/O accesses can be verified.
702
703	  When debugging drivers it is useful to see what I/O accesses were
704	  done and in what order.
705
706	  Even if the individual accesses are of little interest it can be
707	  useful to verify that the access pattern is consistent each time
708	  an operation is performed. In this case a checksum can be used to
709	  characterise the operation of a driver. The checksum can be compared
710	  across different runs of the operation to verify that the driver is
711	  working properly.
712
713	  In particular, when performing major refactoring of the driver, where
714	  the access pattern should not change, the checksum provides assurance
715	  that the refactoring work has not broken the driver.
716
717	  This works by sneaking into the io.h heder for an architecture and
718	  redirecting I/O accesses through iotrace's tracing mechanism.
719
720	  For now no commands are provided to examine the trace buffer. The
721	  format is fairly simple, so 'md' is a reasonable substitute.
722
723	  Note: The checksum feature is only useful for I/O regions where the
724	  contents do not change outside of software control. Where this is not
725	  suitable you can fall back to manually comparing the addresses. It
726	  might be useful to enhance tracing to only checksum the accesses and
727	  not the data read/written.
