/** @file

|
Load File protocol as defined in the UEFI 2.0 specification.
|
||
|
|
|
||
|
|
Load file protocol exists to supports the addition of new boot devices,
|
||
|
|
and to support booting from devices that do not map well to file system.
|
||
|
|
Network boot is done via a LoadFile protocol.
|
||
|
|
|
||
|
|
UEFI 2.0 can boot from any device that produces a LoadFile protocol.
