From 1e9b2bddff2217eb23bf9eb5d1052ecfebc39204 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Tue, 9 Sep 2014 17:59:19 +0000 Subject: EmbeddedPkg: Split off FDT loading functionality from FdtLib Split off the recently added functionality to load device tree images and install them as configuration tables, as it introduces a dependency on UefiBootServicesTableLib, preventing FdtLib from being used during SEC and PEI phases.
