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

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".

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

1243	  Encapsulating data as a blob
1244	  Each time that the Blob Protocol is used to protect data, a
1245	  different randomly generated key is used to encrypt the data.
1246	  This random key is itself encrypted using a key which is derived
1247	  from SoC's non-volatile secret key and a 16 bit Key identifier.
1248	  The resulting encrypted key along with encrypted data is called a
1249	  blob. The non-volatile secure key is available for use only during
1250	  secure boot.
1251
1252	  During decapsulation, the reverse process is performed to get back
1253	  the original data.
1254
1255	  Sub-commands:
1256            blob enc - encapsulating data as a cryptgraphic blob
1257	    blob dec - decapsulating cryptgraphic blob to get the data
1258
1259	  Syntax:
1260
1261	  blob enc src dst len km
1262
1263	  Encapsulate and create blob of data $len bytes long
1264	  at address $src and store the result at address $dst.
1265	  $km is the 16 byte key modifier is also required for
1266	  generation/use as key for cryptographic operation. Key
1267	  modifier should be 16 byte long.
1268
1269	  blob dec src dst len km
1270
1271	  Decapsulate the  blob of data at address $src and
1272	  store result of $len byte at addr $dst.
1273	  $km is the 16 byte key modifier is also required for
1274	  generation/use as key for cryptographic operation. Key
1275	  modifier should be 16 byte long.
