This file declares the Firmware Volume Protocol.
|
|
|
|
The Firmware Volume Protocol provides file-level access to the firmware volume.
|
|
Each firmware volume driver must produce an instance of the Firmware Volume
|
|
Protocol if the firmware volume is to be visible to the system. The Firmware
|
|
Volume Protocol also provides mechanisms for determining and modifying some
|
|
attributes of the firmware volume.
