   4 Subject: [PATCH 1/3] EmbeddedPkg: Added libfdt port
   5
   6 This port is based on the 'libfdt' project (dual licensed BSD/GPL).
   7
   8 Prior to apply this patch you must execute the following steps:
   9
  10 1. Clone the dtc into a temporary directory:
  11 cd EmbeddedPkg/Library
  12 git clone git://git.jdl.com/software/dtc.git
  13
  14 2. Copy the content of 'libfdt' into EmbeddedPkg/Library/FdtLib/
  15 cd dtc
  16 cp -a libfdt ../FdtLib
  17
  18 3. Copy the libfdt headers:
  19 mv ../FdtLib/libfdt.h ../../Include/
  20 mv ../FdtLib/fdt.h ../../Include/
  21 rm ../FdtLib/libfdt_env.h

 205 +How to update EmbeddedPkg/Library/FdtLib
 206 +----------------------------------------
 207 +1. Clone the dtc into a temporary directory:
 208 +git clone git://git.jdl.com/software/dtc.git
 209 +
 210 +2. Copy the content of 'libfdt' into EmbeddedPkg/Library/FdtLib/
 211 +cd dtc
 212 +cp -a libfdt/* $(EDK2_ROOT)/EmbeddedPkg/Library/FdtLib/
 213 +
 214 +3. Copy the libfdt headers:
 215 +mv $(EDK2_ROOT)/EmbeddedPkg/Library/FdtLib/libfdt.h $(EDK2_ROOT)/EmbeddedPkg/Include/
 216 +mv $(EDK2_ROOT)/EmbeddedPkg/Library/FdtLib/fdt.h $(EDK2_ROOT)/EmbeddedPkg/Include/
 217 +rm $(EDK2_ROOT)/EmbeddedPkg/Library/FdtLib/libfdt_env.h
