-Basic support for opening files on different device types. The device string
-is in the form of DevType:Path. Current DevType is required as there is no
-current mounted device concept of current working directory concept implement
-by this library.
-
-Device names are case insensitive and only check the leading characters for
-unique matches. Thus the following are all the same:
-LoadFile0:
-l0:
-L0:
-Lo0:
-
-Supported Device Names:
-A0x1234:0x12 - A memory buffer starting at address 0x1234 for 0x12 bytes
-l1: - EFI LoadFile device one.
-B0: - EFI BlockIo zero.
-fs3: - EFI Simple File System device 3
-Fv2: - EFI Firmware VOlume device 2
-10.0.1.102: - TFTP service IP followed by the file name
