/**
Erases and initializes a firmware volume block.
The EraseBlocks() function erases one or more blocks as denoted
by the variable argument list. The entire parameter list of
blocks must be verified before erasing any blocks. If a block is
requested that does not exist within the associated firmware
volume (it has a larger index than the last block of the
firmware volume), the EraseBlocks() function must return the
status code EFI_INVALID_PARAMETER without modifying the contents
of the firmware volume. Implementations should be mindful that
the firmware volume might be in the WriteDisabled state. If it
is in this state, the EraseBlocks() function must return the
status code EFI_ACCESS_DENIED without modifying the contents of
the firmware volume. All calls to EraseBlocks() must be fully
flushed to the hardware before the EraseBlocks() service
returns.
@param This Indicates the EFI_FIRMWARE_VOLUME_BLOCK2_PROTOCOL
instance.
@param ... The variable argument list is a list of tuples.
Each tuple describes a range of LBAs to erase
and consists of the following:
- An EFI_LBA that indicates the starting LBA
- A UINTN that indicates the number of blocks to
erase
The list is terminated with an
EFI_LBA_LIST_TERMINATOR. For example, the
following indicates that two ranges of blocks
(5-7 and 10-11) are to be erased: EraseBlocks
(This, 5, 3, 10, 2, EFI_LBA_LIST_TERMINATOR);
@retval EFI_SUCCESS The erase request was successfully
completed.
@retval EFI_ACCESS_DENIED The firmware volume is in the
WriteDisabled state.
@retval EFI_DEVICE_ERROR The block device is not functioning
correctly and could not be written.
The firmware device may have been
partially erased.
@retval EFI_INVALID_PARAMETER One or more of the LBAs listed
in the variable argument list do
not exist in the firmware volume.
