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
61	  printf() call, so it may contain '%' format specifications,

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

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