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.

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

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