5	default y
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.

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

44	help
45	  This option enables stopping (aborting) of the automatic
46	  boot feature only by issuing a specific input key or
47	  string. If not enabled, any input key will abort the
48	  U-Boot automatic booting process and bring the device
49	  to the U-Boot prompt for user input.

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,
62	  provided that it also includes, sepearated by commas exactly

77	  a specific input key or string. If CONFIG_AUTOBOOT_DELAY_STR
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
81	  U-Boot prompt will time out if CONFIG_BOOT_RETRY_TIME is
82	  used, otherwise it never times out.
83
84config AUTOBOOT_STOP_STR
85	string "Stop autobooting via specific input key / string"
86	depends on AUTOBOOT_KEYED && !AUTOBOOT_ENCRYPTION
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
94	  times out, even if CONFIG_BOOT_RETRY_TIME is used.

101	  This option allows for the boot sequence to be interrupted
102	  by ctrl-c, in addition to the "bootdelaykey" and "bootstopkey".
103	  Setting this variable	provides an escape sequence from the
104	  limited "password" strings.

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

1251	help
1252	  This is used with the Freescale secure boot mechanism.
1253
1254	  Freescale's SEC block has built-in Blob Protocol which provides
1255	  a method for protecting user-defined data across system power
1256	  cycles. SEC block protects data in a data structure called a Blob,
1257	  which provides both confidentiality and integrity protection.
1258
1259	  Encapsulating data as a blob
1260	  Each time that the Blob Protocol is used to protect data, a
1261	  different randomly generated key is used to encrypt the data.
1262	  This random key is itself encrypted using a key which is derived
1263	  from SoC's non-volatile secret key and a 16 bit Key identifier.
1264	  The resulting encrypted key along with encrypted data is called a
1265	  blob. The non-volatile secure key is available for use only during
1266	  secure boot.
1267
1268	  During decapsulation, the reverse process is performed to get back
1269	  the original data.
1270
1271	  Sub-commands:
