See it for details. They are:\n-\n-  bootdelay\n-  bootcmd\n-  CONFIG_BOOTDELAY\n-  CONFIG_BOOTCOMMAND\n-\n-Some additional options that make autoboot safer in a production\n-product are documented here.\n-\n-Why use them?\n--------------\n-\n-The basic autoboot feature allows a system to automatically boot to\n-the real application (such as Linux) without a user having to enter\n-any commands. If any key is pressed before the boot delay time\n-expires, U-Boot stops the autoboot process, gives a U-Boot prompt\n-and waits forever for a command. That's a good thing if you pressed a\n-key because you wanted to get the prompt.\n-\n-It's not so good if the key press was a stray character on the\n-console serial port, say because a user who knows nothing about\n-U-Boot pressed a key before the system had time to boot. It's even\n-worse on an embedded product that doesn't have a console during\n-normal use. The modem plugged into that console port sends a\n-character at the wrong time and the system hangs, with no clue as to\n-why it isn't working.\n-\n-You might want the system to autoboot to recover after an external\n-configuration program stops autoboot. If the configuration program\n-dies or loses its connection (modems can disconnect at the worst\n-time) U-Boot will patiently wait forever for it to finish.\n-\n-These additional configuration options can help provide a system that\n-boots when it should, but still allows access to U-Boot.\n-\n-What they do\n-------------\n-\n-  CONFIG_BOOT_RETRY_TIME\n-  CONFIG_BOOT_RETRY_MIN\n-\n-  \"bootretry\" environment variable\n-\n-\tThese options determine what happens after autoboot is\n-\tstopped and U-Boot is waiting for commands.\n-\n-\tCONFIG_BOOT_RETRY_TIME must be defined to enable the boot\n-\tretry feature. If the environment variable \"bootretry\" is\n-\tfound then its value is used, otherwise the retry timeout is\n-\tCONFIG_BOOT_RETRY_TIME. CONFIG_BOOT_RETRY_MIN is optional and\n-\tdefaults to CONFIG_BOOT_RETRY_TIME. All times are in seconds.\n-\n-\tIf the retry timeout is negative, the U-Boot command prompt\n-\tnever times out. Otherwise it is forced to be at least\n-\tCONFIG_BOOT_RETRY_MIN seconds. If no valid U-Boot command is\n-\tentered before the specified time the boot delay sequence is\n-\trestarted. Each command that U-Boot executes restarts the\n-\ttimeout.\n-\n-\tIf CONFIG_BOOT_RETRY_TIME < 0 the feature is there, but\n-\tdoesn't do anything unless the environment variable\n-\t\"bootretry\" is >= 0.\n-\n-  CONFIG_AUTOBOOT_KEYED\n-  CONFIG_AUTOBOOT_KEYED_CTRLC\n-  CONFIG_AUTOBOOT_PROMPT\n-  CONFIG_AUTOBOOT_DELAY_STR\n-  CONFIG_AUTOBOOT_STOP_STR\n-\n-  \"bootdelaykey\"  environment variable\n-  \"bootstopkey\"\t  environment variable\n-\n-\tThese options give more control over stopping autoboot. When\n-\tthey are used a specific character or string is required to\n-\tstop or delay autoboot.\n-\n-\tDefine CONFIG_AUTOBOOT_KEYED (no value required) to enable\n-\tthis group of options.\tCONFIG_AUTOBOOT_DELAY_STR,\n-\tCONFIG_AUTOBOOT_STOP_STR or both should be specified (or\n-\tspecified by the corresponding environment variable),\n-\totherwise there is no way to stop autoboot.\n-\n-\tCONFIG_AUTOBOOT_PROMPT is displayed before the boot delay\n-\tselected by CONFIG_BOOTDELAY starts. If it is not defined\n-\tthere is no output indicating that autoboot is in progress.\n-\n-\tNote that CONFIG_AUTOBOOT_PROMPT is used as the (only)\n-\targument to a printf() call, so it may contain '%' format\n-\tspecifications, provided that it also includes, sepearated by\n-\tcommas exactly like in a printf statement, the required\n-\targuments. It is the responsibility of the user to select only\n-\tsuch arguments that are valid in the given context. A\n-\treasonable prompt could be defined as\n-\n-\t\t#define CONFIG_AUTOBOOT_PROMPT \\\n-\t\t\t\"autoboot in %d seconds\\n\",bootdelay\n-\n-\tIf CONFIG_AUTOBOOT_DELAY_STR or \"bootdelaykey\" is specified\n-\tand this string is received from console input before\n-\tautoboot starts booting, U-Boot gives a command prompt. The\n-\tU-Boot prompt will time out if CONFIG_BOOT_RETRY_TIME is\n-\tused, otherwise it never times out.\n-\n-\tIf CONFIG_AUTOBOOT_STOP_STR or \"bootstopkey\" is specified and\n-\tthis string is received from console input before autoboot\n-\tstarts booting, U-Boot gives a command prompt. The U-Boot\n-\tprompt never times out, even if CONFIG_BOOT_RETRY_TIME is\n-\tused.\n-\n-\tThe string recognition is not very sophisticated. If a\n-\tpartial match is detected, the first non-matching character\n-\tis checked to see if starts a new match. There is no check\n-\tfor a shorter partial match, so it's best if the first\n-\tcharacter of a key string does not appear in the rest of the\n-\tstring.\n-\n-\tThe CONFIG_AUTOBOOT_KEYED_CTRLC #define allows for the boot\n-\tsequence to be interrupted by ctrl-c, in addition to the\n-\t\"bootdelaykey\" and \"bootstopkey\". Setting this variable\n-\tprovides an escape sequence from the limited \"password\"\n-\tstrings.\n-\n-  CONFIG_AUTOBOOT_ENCRYPTION\n-\n-  \"bootstopkeysha256\"\tenvironment variable\n-\n-\t- Hash value of the input which unlocks the device and\n-\t  stops autoboot.\n-\n-\tThis option allows a string to be entered into U-Boot to stop the\n-\tautoboot. The string itself is hashed and compared against the hash\n-\tin the environment variable 'bootstopkeysha256'. If it matches then\n-\tboot stops and a command-line prompt is presented.\n-\n-\tThis provides a way to ship a secure production device which can also\n-\tbe accessed at the U-Boot command line.\n-\n-  CONFIG_RESET_TO_RETRY\n-\n-\t(Only effective when CONFIG_BOOT_RETRY_TIME is also set)\n-\tAfter the countdown timed out, the board will be reset to restart\n-\tagain.\n-\n-  CONFIG_AUTOBOOT_USE_MENUKEY\n-  CONFIG_AUTOBOOT_MENUKEY\n-\n-\tIf this key is pressed to stop autoboot, then the commands in the\n-\tenvironment variable 'menucmd' will be executed before boot starts.\n-\tFor example, 33 means \"!\" in ASCII, so pressing ! at boot would take\n-\tthis action.\ndiff --git a/doc/usage/autoboot.rst b/doc/usage/autoboot.rst\nnew file mode 100644\nindex 00000000000..3b6f040008b\n--- /dev/null\n+++ b/doc/usage/autoboot.rst\n@@ -0,0 +1,149 @@\n+..

It is the responsibility\n+    of the user to select only such arguments that are valid in\n+    the given context. A reasonable prompt could be defined as\n+\n+    ::\n+\n+        #define CONFIG_AUTOBOOT_PROMPT \\\n+                \"\\rBooting in %d seconds\"\n+\n+CONFIG_RESET_TO_RETRY\n+    (Only effective when CONFIG_BOOT_RETRY_TIME is also set)\n+    After the countdown timed out, the board will be reset to restart\n+    again.\n+\n+CONFIG_AUTOBOOT_USE_MENUKEY, CONFIG_AUTOBOOT_MENUKEY\n+    If this key is pressed to stop autoboot, then the commands in the\n+    environment variable 'menucmd' will be executed before boot starts.\n+    For example, 33 means \"!\" in ASCII, so pressing ! at boot would take\n+    this action.\n+\n+\n+Controlling autoboot\n+~~~~~~~~~~~~~~~~~~~~\n+\n+The following options give more control over stopping autoboot. When\n+they are used a specific character or string is required to stop or\n+delay autoboot.\n+Define CONFIG_AUTOBOOT_KEYED (no value required) to enable this group\n+of options.\n+\n+CONFIG_AUTOBOOT_DELAY_STR, CONFIG_AUTOBOOT_STOP_STR or both\n+should be specified (or specified by the corresponding environment variable),\n+otherwise there is no way to stop autoboot.\n+\n+CONFIG_AUTOBOOT_DELAY_STR, \"bootdelaykey\" environment variable\n+    If specified and this string is received from console input\n+    before autoboot starts booting, U-Boot gives a command prompt.\n+    The U-Boot prompt will time out if CONFIG_BOOT_RETRY_TIME is\n+    used, otherwise it never times out. It should be specified\n+    otherwise there is no way to stop autoboot.\n+\n+CONFIG_AUTOBOOT_STOP_STR, \"bootstopkey\" environment variable\n+    If specified and this string is received from console input\n+    before autoboot starts booting, U-Boot gives a command prompt.\n+    The U-Boot prompt never times out, even if CONFIG_BOOT_RETRY_TIME\n+    is used.\n+\n+The string recognition is not very sophisticated. If a\n+partial match is detected, the first non-matching character\n+is checked to see if starts a new match. There is no check\n+for a shorter partial match, so it's best if the first\n+character of a key string does not appear in the rest of the\n+string.\n+\n+CONFIG_AUTOBOOT_KEYED_CTRLC\n+    The CONFIG_AUTOBOOT_KEYED_CTRLC #define allows for the boot\n+    sequence to be interrupted by ctrl-c, in addition to the\n+    \"bootdelaykey\" and \"bootstopkey\". Setting this variable\n+    provides an escape sequence from the limited \"password\"\n+    strings.\n+\n+CONFIG_AUTOBOOT_ENCRYPTION, \"bootstopkeysha256\" environment variable\n+    This option allows a string to be entered into U-Boot to stop the\n+    autoboot. The string itself is hashed and compared against the hash\n+    in the environment variable 'bootstopkeysha256'. If it matches then\n+    boot stops and a command-line prompt is presented.\n+\n+    This provides a way to ship a secure production device which can also\n+    be accessed at the U-Boot command line.\ndiff --git a/doc/usage/index.rst b/doc/usage/index.rst\nindex 6f477b842ca..35b9f4612f4 100644\n--- a/doc/usage/index.rst\n+++ b/doc/usage/index.rst\n@@ -4,6 +4,7 @@ Use U-Boot\n .. toctree::\n    :maxdepth: 1\n \n+   autoboot\n    spl_boot\n    blkmap\n    dfu\n",
