/*++
Routine Description:
Return the graphics image file named FileNameGuid into Image and return it's
size in ImageSize. All Firmware Volumes (FV) in the system are searched for the
file name.
Arguments:
FileNameGuid - File Name of graphics file in the FV(s).
Image - Pointer to pointer to return graphics image. If NULL, a
buffer will be allocated.
ImageSize - Size of the graphics Image in bytes. Zero if no image found.
Returns:
EFI_SUCCESS - Image and ImageSize are valid.
EFI_BUFFER_TOO_SMALL - Image not big enough. ImageSize has required size
EFI_NOT_FOUND - FileNameGuid not found

Routine Description:
Return the graphics image file named FileNameGuid into Image and return it's
size in ImageSize. All Firmware Volumes (FV) in the system are searched for the
file name.
Arguments:
ImageHandle - The driver image handle of the caller. The parameter is used to
optimize the loading of the image file so that the FV from which
the driver image is loaded will be tried first.
FileNameGuid - File Name of graphics file in the FV(s).
Image - Pointer to pointer to return graphics image. If NULL, a
buffer will be allocated.
ImageSize - Size of the graphics Image in bytes. Zero if no image found.
Returns:
EFI_SUCCESS - Image and ImageSize are valid.

/*++
Routine Description:
Convert a *.BMP graphics image to a GOP/UGA blt buffer. If a NULL Blt buffer
is passed in a GopBlt buffer will be allocated by this routine. If a GopBlt
buffer is passed in it will be used if it is big enough.
Arguments:
BmpImage - Pointer to BMP file
BmpImageSize - Number of bytes in BmpImage
GopBlt - Buffer containing GOP version of BmpImage.
GopBltSize - Size of GopBlt in bytes.
PixelHeight - Height of GopBlt/BmpImage in pixels
PixelWidth - Width of GopBlt/BmpImage in pixels
Returns:
EFI_SUCCESS - GopBlt and GopBltSize are returned.
EFI_UNSUPPORTED - BmpImage is not a valid *.BMP image
EFI_BUFFER_TOO_SMALL - The passed in GopBlt buffer is not big enough.
GopBltSize will contain the required size.
EFI_OUT_OF_RESOURCES - No enough buffer to allocate

Routine Description:
Use Console Control Protocol to lock the Console In Spliter virtual handle.
This is the ConInHandle and ConIn handle in the EFI system table. All key
presses will be ignored until the Password is typed in. The only way to
disable the password is to type it in to a ConIn device.
Arguments:
Password - Password used to lock ConIn device
Returns:
EFI_SUCCESS - ConsoleControl has been flipped to graphics and logo
displayed.
