2) Change EFI_FVB_ATTRIBUTE to EFI_FVB2_ATTRIBUTE, As Zimmer, Vincent’s PI1.0 errata document said, in PI we need use EFI_FVB2_ATTRIBUTE to differ the specification change. 3) Remove duplicate definition of SERIAL_MODE, PARALLEL_MODE in Include\Framework\Legacy16.h 4) Remove EFI_FV_FILE_ATTRIB_FIXED and EFI_FV_FILE_ATTRIB_ALIGNMENT from IntelFrameworkPkg\Include\Protocol\FirmwareVolume.h, because they defined in PI specification. 5) Remove EFI_FORM_LABEL from IntelFrameworkPkg\Include\Protocol\HiiFramework.h git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@3333 6f19259b-4bc3-4df7-8a09-765794883524

@par Protocol Description:
|
|
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.
|
|
|
|
@param GetVolumeAttributes
|
|
Retrieves volume capabilities and current settings.
|
|
|
|
@param SetVolumeAttributes
|
|
Modifies the current settings of the firmware volume.
|
|
|
|
@param ReadFile
|
|
Reads an entire file from the firmware volume.
|
|
|
|
@param ReadSection
|
|
Reads a single section from a file into a buffer.
|
|
|
|
@param WriteFile
|
|
Writes an entire file into the firmware volume.
|
|
|
|
@param GetNextFile
|
|
Provides service to allow searching the firmware volume.
|
|
|
|
@param KeySize
|
|
Data field that indicates the size in bytes of the Key input buffer for
|
|
the GetNextFile() API.
|
|
|
|
@param ParentHandle
|
|
Handle of the parent firmware volume.
