+Lauching UEFI images
+--------------------
+
+Bootefi command
+~~~~~~~~~~~~~~~
+
+The bootefi command is used to start UEFI applications or to install UEFI
+drivers. It takes two parameters
+
+ bootefi <image address> [fdt address]
+
+* image address - the memory address of the UEFI binary
+* fdt address - the memory address of the flattened device tree
+
+The environment variable 'bootargs' is passed as load options in the UEFI system
+table. The Linux kernel EFI stub uses the load options as command line
+arguments.

+
+Boot manager
+~~~~~~~~~~~~
+
+The UEFI specification foresees to define boot entries and boot sequence via UEFI
+variables. Booting according to these variables is possible via
+
+ bootefi bootmgr [fdt address]
+
+* fdt address - the memory address of the flattened device tree
+
+The relevant variables are:
+
+* Boot0000-BootFFFF define boot entries
+* BootNext specifies next boot option to be booted
+* BootOrder specifies in which sequence the boot options shall be tried if
+ BootNext is not defined or booting via BootNext fails

+Efidebug command
+~~~~~~~~~~~~~~~~
+
+The efidebug command is used to set and display boot options as well as to
+display information about internal data of the UEFI subsystem (devices,
+drivers, handles, loaded images, and the memory map).
