+bootelf command
+===============
+
+Synopsis
+--------
+
+::
+
+ bootelf [-p|-s] [-d <fdt_addr>] [<image_addr> [<arg>]...]
+
+Description
+-----------
+
+The *bootelf* command is used to launch a ELF binary at *image_addr*. If
+*image_addr* is not specified, the bootelf command will try to find image in
+*image_load_addr* variable (*CONFIG\_SYS\_LOAD\_ADDR* by default).
+
+Args after *image_addr* will be passed to application in common *argc*, *argv*
+format.
+
+A command sequence to run a ELF image using FDT might look like
+
+::
+
+ load mmc 0:1 ${loadaddr} /kernel.elf
+ load mmc 0:1 ${fdt_addr_r} /soc-board.dtb
+ bootelf -d ${fdt_addr_r} ${loadaddr} ${loadaddr}
+
+image_addr
+ Address of the ELF binary.
+
+fdt_addr
+ Address of the device-tree. This argument in only needed if bootable
+ application uses FDT that requires additional setup (like /memory node).
+
+arg
+ Any text arguments for bootable application. This is usually the address
+ of the device-tree.
+
+Flags:
+
+-p|-s
+ Load ELF image via program headers (-p) or via section headers (-s).
+
+-d
+ Setup FDT by address.
+
+Configuration
+-------------
+
+The bootelf command is only available if CONFIG_CMD_ELF=y. FDT setup by flag -d
+need CONFIG_CMD_ELF_FDT_SETUP=y.
