1 /** @file 2 The device path protocol as defined in UEFI 2.0. 3 4 The device path represents a programmatic path to a device, 5 from a software point of view. The path must persist from boot to boot, so 6 it can not contain things like PCI bus numbers that change from boot to boot. 7 8 Copyright (c) 2006 - 2016, Intel Corporation.
