Subject: [PATCH 1/3] EmbeddedPkg: Added libfdt port
This port is based on the 'libfdt' project (dual licensed BSD/GPL).
Prior to apply this patch you must execute the following steps:
1. Clone the dtc into a temporary directory:
cd EmbeddedPkg/Library
git clone git://git.jdl.com/software/dtc.git
2. Copy the content of 'libfdt' into EmbeddedPkg/Library/FdtLib/
cd dtc
cp -a libfdt ../FdtLib
3. Copy the libfdt headers:
mv ../FdtLib/libfdt.h ../../Include/
mv ../FdtLib/fdt.h ../../Include/
rm ../FdtLib/libfdt_env.h
