If disabled, you get the old, much simpler behaviour with a somewhat smaller memory footprint. config SYS_HUSH_PARSER bool help Backward compatibility. config SYS_PROMPT string "Shell prompt" default "=> " help This string is displayed in the command line to the left of the cursor. menu "Autoboot options" config AUTOBOOT_KEYED bool "Stop autobooting via specific input key / string" help This option enables stopping (aborting) of the automatic boot feature only by issuing a specific input key or string. If not enabled, any input key will abort the U-Boot automatic booting process and bring the device to the U-Boot prompt for user input. config AUTOBOOT_PROMPT string "Autoboot stop prompt" depends on AUTOBOOT_KEYED default "Autoboot in %d seconds\\n" help This string is displayed before the boot delay selected by CONFIG_BOOTDELAY starts. If it is not defined there is no output indicating that autoboot is in progress. Note that this define is used as the (only) argument to a printf() call, so it may contain '%' format specifications, provided that it also includes, sepearated by commas exactly like in a printf statement, the required arguments. It is the responsibility of the user to select only such arguments that are valid in the given context. config AUTOBOOT_ENCRYPTION bool "Enable encryption in autoboot stopping" depends on AUTOBOOT_KEYED config AUTOBOOT_DELAY_STR string "Delay autobooting via specific input key / string" depends on AUTOBOOT_KEYED && !AUTOBOOT_ENCRYPTION help This option delays the automatic boot feature by issuing a specific input key or string. If CONFIG_AUTOBOOT_DELAY_STR or the environment variable "bootdelaykey" is specified and this string is received from console input before autoboot starts booting, U-Boot gives a command prompt. The U-Boot prompt will time out if CONFIG_BOOT_RETRY_TIME is used, otherwise it never times out. config AUTOBOOT_STOP_STR string "Stop autobooting via specific input key / string" depends on AUTOBOOT_KEYED && !AUTOBOOT_ENCRYPTION help This option enables stopping (aborting) of the automatic boot feature only by issuing a specific input key or string. If CONFIG_AUTOBOOT_STOP_STR or the environment variable "bootstopkey" is specified and this string is received from console input before autoboot starts booting, U-Boot gives a command prompt. The U-Boot prompt never times out, even if CONFIG_BOOT_RETRY_TIME is used. config AUTOBOOT_KEYED_CTRLC bool "Enable Ctrl-C autoboot interruption" depends on AUTOBOOT_KEYED && !AUTOBOOT_ENCRYPTION help This option allows for the boot sequence to be interrupted by ctrl-c, in addition to the "bootdelaykey" and "bootstopkey". Setting this variable provides an escape sequence from the limited "password" strings. config AUTOBOOT_STOP_STR_SHA256 string "Stop autobooting via SHA256 encrypted password" depends on AUTOBOOT_KEYED && AUTOBOOT_ENCRYPTION help This option adds the feature to only stop the autobooting, and therefore boot into the U-Boot prompt, when the input string / password matches a values that is encypted via a SHA256 hash and saved in the environment. endmenu comment "Commands" menu "Info commands" config CMD_BDI bool "bdinfo" default y help Print board info config CMD_CONSOLE bool "coninfo" default y help Print console devices and information. config CMD_CPU bool "cpu" help Print information about available CPUs.

To use this properly you will need to enable one or both of the demo devices (DM_DEMO_SHAPE and DM_DEMO_SIMPLE). Otherwise you will always get an empty list of devices.

The server will copy the ID from client requests to responses and U-Boot will use this to determine if it is the destination of an incoming response. Some servers will check that addresses aren't in use before handing them out (usually using an ARP ping) and therefore take up to a few hundred milliseconds to respond. Network congestion may also influence the time it takes for a response to make it back to the client. If that time is too long, U-Boot will retransmit requests. In order to allow earlier responses to still be accepted after these retransmissions, U-Boot's BOOTP client keeps a small cache of IDs. The CONFIG_BOOTP_ID_CACHE_SIZE controls the size of this cache. The default is to keep IDs for up to four outstanding requests. Increasing this will allow U-Boot to accept offers from a BOOTP client in networks with unusually high latency. config BOOTP_MAY_FAIL bool "Do not start over, if DHCP server is not available" help If the DHCP server is not found after the configured retry count, the call will fail instead of starting over. This can be used to fail over to Link-local IP address configuration if the DHCP server is not available. config BOOTP_NISDOMAIN bool "obtain NIS domain from DHCP" config BOOTP_NTPSERVER bool "obtain NTP server IP address from DHCP" config BOOTP_RANDOM_DELAY bool "Use a (pseudo) random delay between DHCP retries" select LIB_RAND config BOOTP_RANDOM_ID bool "Generate a (pseudo) random transaction ID" select LIB_RAND config BOOTP_SEND_HOSTNAME bool "send hostname in DHCP request" config BOOTP_SUBNETMASK bool "obtain subnet mask from DHCP" config BOOTP_TIMEOFFSET bool "obtain from DHCP" config BOOTP_VENDOREX bool "obtain from DHCP" endmenu endif config CMD_NFS bool "nfs" default y help Boot image via network using NFS protocol. config CMD_PING bool "ping" help Send ICMP ECHO_REQUEST to network host config CMD_CDP bool "cdp" help Perform CDP network configuration config CMD_SNTP bool "sntp" help Synchronize RTC via network config CMD_DNS bool "dns" help Lookup the IP of a hostname config CMD_LINK_LOCAL bool "linklocal" help Acquire a network IP address using the link-local protocol config CMD_MII bool "MII register access" help Support reading/writing ETH PHY registers via MII bus endmenu menu "Misc commands" config CMD_CACHE bool "cache control" help Enable commands to switch data cache on/off. config CMD_TIME bool "time" help Run commands and summarize execution time. config CMD_FUSE bool "fuse read/write" help eFuse reading and programming support # TODO: rename to CMD_SLEEP config CMD_MISC bool "sleep" default y help Delay execution for some time config CMD_TIMER bool "timer" help Access the system timer. config CMD_SETGETDCR bool "getdcr, setdcr, getidcr, setidcr" depends on 4xx default y help getdcr - Get an AMCC PPC 4xx DCR's value setdcr - Set an AMCC PPC 4xx DCR's value getidcr - Get a register value via indirect DCR addressing setidcr - Set a register value via indirect DCR addressing config CMD_SOUND bool "sound" depends on SOUND help This provides basic access to the U-Boot's sound support. The main feature is to play a beep. sound init - set up sound system sound play - play a sound endmenu menu "Boot timing" config BOOTSTAGE bool "Boot timing and reporting" help Enable recording of boot time while booting. To use it, insert calls to bootstage_mark() with a suitable BOOTSTAGE_ID from bootstage.h. Only a single entry is recorded for each ID. You can give the entry a name with bootstage_mark_name(). You can also record elapsed time in a particular stage using bootstage_start() before starting and bootstage_accum() when finished. Bootstage will add up all the accumated time and report it. Normally, IDs are defined in bootstage.h but a small number of additional 'user' IDs can be used but passing BOOTSTAGE_ID_ALLOC as the ID. Calls to show_boot_progress() wil also result in log entries but these will not have names. config BOOTSTAGE_REPORT bool "Display a detailed boot timing report before booting the OS" depends on BOOTSTAGE help Enable output of a boot time report just before the OS is booted. This shows how long it took U-Boot to go through each stage of the boot process. The report looks something like this: Timer summary in microseconds: Mark Elapsed Stage 0 0 reset 3,575,678 3,575,678 board_init_f start 3,575,695 17 arch_cpu_init A9 3,575,777 82 arch_cpu_init done 3,659,598 83,821 board_init_r start 3,910,375 250,777 main_loop 29,916,167 26,005,792 bootm_start 30,361,327 445,160 start_kernel config BOOTSTAGE_USER_COUNT hex "Number of boot ID numbers available for user use" default 20 help This is the number of available user bootstage records. Each time you call bootstage_mark(BOOTSTAGE_ID_ALLOC, ...) a new ID will be allocated from this stash. If you exceed the limit, recording will stop. config CMD_BOOTSTAGE bool "Enable the 'bootstage' command" depends on BOOTSTAGE help Add a 'bootstage' command which supports printing a report and un/stashing of bootstage data. config BOOTSTAGE_FDT bool "Store boot timing information in the OS device tree" depends on BOOTSTAGE help Stash the bootstage information in the FDT. A root 'bootstage' node is created with each bootstage id as a child. Each child has a 'name' property and either 'mark' containing the mark time in microsecond, or 'accum' containing the accumulated time for that bootstage id in microseconds. For example: bootstage { 154 { name = "board_init_f"; mark = <3575678>; }; 170 { name = "lcd"; accum = <33482>; }; }; Code in the Linux kernel can find this in /proc/devicetree. config BOOTSTAGE_STASH bool "Stash the boot timing information in memory before booting OS" depends on BOOTSTAGE help Some OSes do not support device tree. Bootstage can instead write the boot timing information in a binary format at a given address. This happens through a call to bootstage_stash(), typically in the CPU's cleanup_before_linux() function. You can use the 'bootstage stash' and 'bootstage unstash' commands to do this on the command line. config BOOTSTAGE_STASH_ADDR hex "Address to stash boot timing information" default 0 help Provide an address which will not be overwritten by the OS when it starts, so that it can read this information when ready. config BOOTSTAGE_STASH_SIZE hex "Size of boot timing stash region" default 4096 help This should be large enough to hold the bootstage stash.
