Routine Description:
Erases and initializes a specified range of a firmware volume
Arguments:
Instance - The FV instance to be erased
StartLba - The starting logical block index to be erased
OffsetStartLba - Offset into the starting block at which to
begin erasing
LastLba - The last logical block index to be erased
OffsetStartLba - Offset into the last block at which to end erasing
Global - Pointer to ESAL_FWB_GLOBAL that contains all
instance data
Virtual - Whether CPU is in virtual or physical mode
Returns:
EFI_SUCCESS - The firmware volume was erased successfully
EFI_ACCESS_DENIED - The firmware volume is in the WriteDisabled state
EFI_DEVICE_ERROR - The block device is not functioning correctly and
could not be written. Firmware device may have been
partially erased
