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).
