Synopsis

::

Description
 | 
						|
-----------
 | 
						|
 | 
						|
The *efi* command provides information about the EFI environment U-Boot is
 | 
						|
running in, when it is started from EFI.
 | 
						|
 | 
						|
When running as an EFI app, this command queries EFI boot services for the
 | 
						|
information. When running as an EFI payload, EFI boot services have been
 | 
						|
stopped, so it uses the information collected by the boot stub before that
 | 
						|
happened.
 | 
						|
 | 
						|
efi mem
 | 
						|
~~~~~~~
 | 
						|
 | 
						|
This shows the EFI memory map, sorted in order of physical address.
 | 
						|
 | 
						|
This is normally a very large table. To help reduce the amount of detritus,
 | 
						|
boot-time memory is normally merged with conventional memory. Use the 'all'
 | 
						|
argument to show everything.
 | 
						|
 | 
						|
The fields are as follows:
 | 
						|
 | 
						|
#
 | 
						|
    Entry number (sequentially from 0)
 | 
						|
 | 
						|
Type
 | 
						|
    Memory type. EFI has a large number of memory types. The type is shown in
 | 
						|
    the format <n>:<name> where in is the format number in hex and <name> is the
 | 
						|
    name.
 | 
						|
 | 
						|
Physical
 | 
						|
    Physical address
 | 
						|
 | 
						|
Virtual
 | 
						|
    Virtual address
 | 
						|
 | 
						|
Size
 | 
						|
    Size of memory area in bytes
 | 
						|
 | 
						|
Attributes
 | 
						|
    Shows a code for memory attributes. The key for this is shown below the
 | 
						|
    table.
 | 
						|
 | 
						|
efi tables
 | 
						|
~~~~~~~~~~
 | 
						|
 | 
						|
This shows a list of the EFI tables provided in the system table. These use
 | 
						|
GUIDs so it is not possible in general to show the name of a table. But some
 | 
						|
effort is made to provide a useful table, where the GUID is known by U-Boot.
 | 
						|
