 This document describes how to build ARM Trusted Firmware and run it with a
 tested set of other software components using defined configurations on the Juno
 ARM development platform and ARM Fixed Virtual Platform (FVP) models. It is
 possible to use other software components, configurations and platforms but that
 is outside the scope of this document.

-4.  Building the Trusted Firmware
+4.  Getting the Trusted Firmware source code
+--------------------------------------------
+
+The Trusted Firmware source code can be obtained as part of the standard Linaro
+releases, which provide a full software stack, including the Trusted Firmware,
+normal world firmware, Linux kernel and device tree, file system as well as any
+additional micro-controller firmware required by the platform. Please follow the
+instructions on the [Linaro release notes][Linaro releases], section 2.2
+"Downloading the software sources" and section 2.3 "Downloading the filesystem
+binaries".
+
+Note: Both the LSK kernel or the latest tracking kernel can be used along the
+ARM Trusted Firmware, choose the one that best suits your needs.
+
+The Trusted Firmware source code can then be found in the `arm-tf/` directory.
+This is the full git repository cloned from Github. The revision checked out by
+the `repo` tool is indicated by the manifest file. Depending on the manifest
+file you're using, this might not be the latest development version. To
+synchronize your copy of the repository and get the latest updates, use the
+following commands:
+
+    # Change to the Trusted Firmware directory.
+    cd arm-tf
+
+    # Download the latest code from Github.
+    git fetch github
+
+    # Update your working copy to the latest master.
+    # This command will create a local branch master that tracks the remote
+    # branch master from Github.
+    git checkout --track github/master
+
+
+Alternatively, the Trusted Firmware source code can be fetched on its own
+from GitHub:
+
+    git clone https://github.com/ARM-software/arm-trusted-firmware.git
+
+However, the rest of this document assumes that you got the Trusted Firmware
+as part of the Linaro release.

-5.  Obtaining the normal world software
----------------------------------------
+6.  Building the rest of the software stack
+-------------------------------------------
 
-### Obtaining EDK2
+The Linaro release provides a set of scripts that automate the process of
+building all components of the software stack. However, the scripts only support
+a limited number of Trusted Firmware build options. Therefore, it is recommended
+to modify these scripts to build all components except Trusted Firmware, and
+build Trusted Firmware separately as described in the section "Building the
+Trusted Firmware" above.
 
-Potentially any kind of non-trusted firmware may be used with the ARM Trusted
-Firmware but the software has only been tested with the EFI Development Kit 2
-(EDK2) open source implementation of the UEFI specification.
+The instructions below are targeted at an OpenEmbedded filesystem.
 
-To build the software to be compatible with the Foundation and Base FVPs, or the
-Juno platform, follow these steps:
+1.  To exclude Trusted Firmware from the automated build process, edit the
+    variant file `build-scripts/variants/<platform>-oe`, where `<platform>`
+    is either `fvp` or `juno`. Add the following lines at the end of the file:
 
-1.  Clone the [EDK2 source code][EDK2] from GitHub:
+        # Disable ARM Trusted Firmware build
+        ARM_TF_BUILD_ENABLED=0
 
-        git clone -n https://github.com/tianocore/edk2.git
+2.  Launch the build script:
 
-    Not all required features are available in the EDK2 mainline yet. These can
-    be obtained from the ARM-software EDK2 repository instead:
+        CROSS_COMPILE=aarch64-linux-gnu- \
+        build-scripts/build-all.sh <platform>-oe
 
-        cd edk2
-        git remote add -f --tags arm-software https://github.com/ARM-software/edk2.git
-        git checkout --detach v3.0
+### Preparing the Firmware Image Package
 
-2.  Copy build config templates to local workspace
+The EDK2 binary should be specified as `BL33` in the `make` command line when
+building the Trusted Firmware. See the "Building the Trusted Firmware" section
+above. The EDK2 binary for use with the ARM Trusted Firmware can be found here:

+        UEFI_BUILD_MODE=RELEASE
 
-        The EDK2 binary for use with the ARM Trusted Firmware can then be found
-        here:
+*   On FVP, if legacy GICv2 locations are used, the EDK2 platform makefile must
+    be updated. This is required as EDK2 does not support probing for the GIC
+    location. To do this, first clean the EDK2 build directory:
 
-             Build/ArmVExpress-FVP-AArch64/RELEASE_GCC49/FV/FVP_AARCH64_EFI.fd
+        build-scripts/build-uefi.sh fvp-oe clean
 
-    2.  Build for Juno
+    Then edit the following file:
 
-            GCC49_AARCH64_PREFIX=<absolute-path-to-aarch64-gcc>/bin/aarch64-none-elf- \
-            make -f ArmPlatformPkg/ArmJunoPkg/Makefile EDK2_ARCH=AARCH64 \
-            EDK2_TOOLCHAIN=GCC49 EDK2_BUILD=RELEASE
+        uefi/edk2/ArmPlatformPkg/ArmVExpressPkg/ArmVExpress-FVP-AArch64.mak
 
-        The EDK2 binary for use with the ARM Trusted Firmware can then be found
-        here:
-
-            Build/ArmJuno/RELEASE_GCC49/FV/BL33_AP_UEFI.fd
-
-    The EDK2 binary should be specified as `BL33` in in the `make` command line
-    when building the Trusted Firmware. See the "Building the Trusted Firmware"
-    section above.
-
-5.  (Optional) To build EDK2 in debug mode, remove `EDK2_BUILD=RELEASE` from the
-    command line.
-
-6.  (Optional) To boot Linux using a VirtioBlock file-system, the command line
-    passed from EDK2 to the Linux kernel must be modified as described in the
-    "Obtaining a root file-system" section below.
-
-7.  (Optional) If legacy GICv2 locations are used, the EDK2 platform description
-    must be updated. This is required as EDK2 does not support probing for the
-    GIC location. To do this, first clean the EDK2 build directory.
-
-        make -f ArmPlatformPkg/Scripts/Makefile EDK2_ARCH=AARCH64          \
-        EDK2_DSC=ArmPlatformPkg/ArmVExpressPkg/ArmVExpress-FVP-AArch64.dsc \
-        EDK2_TOOLCHAIN=ARMGCC clean
-
-    Then rebuild EDK2 as described in step 3, using the following flag:
+    and add the following build flag into the `EDK2_MACROS` variable:
 
         -D ARM_FVP_LEGACY_GICV2_LOCATION=1
 
+    Then rebuild everything as described above in step 2.
+
     Finally rebuild the Trusted Firmware to generate a new FIP using the
     instructions in the "Building the Trusted Firmware" section.
 
 
-### Obtaining a Linux kernel
-
-Preparing a Linux kernel for use on the FVPs can be done as follows
-(GICv2 support only):
-

-
-        git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
-
-    Not all required features are available in the kernel mainline yet. These
-    can be obtained from the ARM-software Linux repository instead:
-
-        cd linux
-        git remote add -f --tags arm-software https://github.com/ARM-software/linux.git
-        git checkout --detach 1.6-Juno
-

-### Obtaining a root file-system
-
-To prepare a Linaro LAMP based Open Embedded file-system, the following
-instructions can be used as a guide. The file-system can be provided to Linux
-via VirtioBlock or as a RAM-disk. Both methods are described below.
-
-#### Prepare VirtioBlock
-
-To prepare a VirtioBlock file-system, do the following:
-
-1.  Download and unpack the disk image.
-
-    NOTE: The unpacked disk image grows to 3 GiB in size.
-
-        wget http://releases.linaro.org/15.03/members/arm/openembedded/aarch64/vexpress64-openembedded_lamp-armv8-gcc-4.9_20150324-715.img.gz
-        gunzip vexpress64-openembedded_lamp-armv8-gcc-4.9_20150324-715.img.gz
-
-2.  Make sure the Linux kernel has Virtio support enabled using
-    `make ARCH=arm64 menuconfig`.
-
-        Device Drivers  ---> Virtio drivers  ---> <*> Platform bus driver for memory mapped virtio devices
-        Device Drivers  ---> [*] Block devices  --->  <*> Virtio block driver
-        File systems    ---> <*> The Extended 4 (ext4) filesystem
-
-    If some of these configurations are missing, enable them, save the kernel
-    configuration, then rebuild the kernel image using the instructions
-    provided in the section "Obtaining a Linux kernel".
-
-3.  Change the Kernel command line to include `root=/dev/vda2`. This can either
-    be done in the EDK2 boot menu or in the platform file. Editing the platform
-    file and rebuilding EDK2 will make the change persist. To do this:
-
-    1.  In EDK2, edit the following file:
-
-            ArmPlatformPkg/ArmVExpressPkg/ArmVExpress-FVP-AArch64.dsc
-
-    2.  Add `root=/dev/vda2` to:
-
-            gArmPlatformTokenSpaceGuid.PcdDefaultBootArgument|"<Other default options>"
-
-    3.  Remove the entry:
-
-            gArmPlatformTokenSpaceGuid.PcdDefaultBootInitrdPath|""
-
-    4.  Rebuild EDK2 (see "Obtaining UEFI" section above).
-
-4.  The file-system image file should be provided to the model environment by
-    passing it the correct command line option. In the FVPs the following
-    option should be provided in addition to the ones described in the
-    "Running the software on FVP" section below.
-
-    NOTE: A symbolic link to this file cannot be used with the FVP; the path
-    to the real file must be provided.
-
-    On the Base FVPs:
-
-        -C bp.virtioblockdevice.image_path="<path-to>/<file-system-image>"
-
-    On the Foundation FVP:
-
-        --block-device="<path-to>/<file-system-image>"
-
-5.  Ensure that the FVP doesn't output any error messages. If the following
-    error message is displayed:
-
-        ERROR: BlockDevice: Failed to open "<path-to>/<file-system-image>"!
-
-    then make sure the path to the file-system image in the model parameter is
-    correct and that read permission is correctly set on the file-system image
-    file.
-
-#### Prepare RAM-disk
-
-To prepare a RAM-disk root file-system, do the following:
-
-1.  Download the file-system image:
-
-        wget http://releases.linaro.org/15.03/members/arm/openembedded/aarch64/linaro-image-lamp-genericarmv8-20150323-747.rootfs.tar.gz
-
-2.  Modify the Linaro image:
-
-        # Prepare for use as RAM-disk. Normally use MMC, NFS or VirtioBlock.
-        # Be careful, otherwise you could damage your host file-system.
-        mkdir tmp; cd tmp
-        sudo sh -c "zcat ../linaro-image-lamp-genericarmv8-20150323-747.rootfs.tar.gz | cpio -id"
-        sudo ln -s sbin/init .

 ### Preparing Trusted Firmware images
 
-To execute the versions of software components on Juno referred to in this
-document, the latest [Juno Board Recovery Image] must be installed. If you
-have an earlier version installed or are unsure which version is installed,
-follow the recovery image update instructions in the [Juno Software Guide]
-on the [ARM Connected Community] website.
-
-Note that you must use the board recovery image provided in the Juno R1 Initial
-Alpha release, even for Juno R0. This is because the Trusted Firmware now
-supports the new [SCPI v1.0 final protocol][Juno SCP Protocols v1.0]
-exclusively, which is not compatible with the SCP firmware provided in the
-latest Juno R0 release. Although the Juno R1 Initial Alpha release is generally
-not recommended for use with Juno R0 boards, it is suitable for Trusted Firmware
-development.
-
-The Juno platform requires a BL0 and a BL3-0 image to boot up. The BL0 image
+The Juno platform requires a BL0 and a BL30 image to boot up. The BL0 image
 contains the ROM firmware that runs on the SCP (System Control Processor),
-whereas the BL3-0 image contains the SCP Runtime firmware. Both images are
-embedded within the [Juno Board Recovery Image] but they can also be downloaded
-directly: [Juno SCP ROM Firmware] and [Juno SCP Runtime Firmware].
+whereas the BL30 image contains the SCP Runtime firmware. Both images are
+embedded within the Juno board recovery image, these are the files `bl0.bin`
+and `bl30.bin`.
 
-Rebuild the Trusted Firmware specifying the BL3-0 image. Refer to the section
-"Building the Trusted Firmware". Alternatively, the FIP image can be updated
-manually with the BL3-0 image:
+The BL30 file must be part of the FIP image. Therefore, its path must be
+supplied using the `BL30` variable on the command line when building the
+FIP. Please refer to the section "Building the Trusted Firmware".
 
-    fip_create --dump --bl30 <path-to>/<bl30-binary> <path-to>/<FIP-binary>

-### Obtaining the Flattened Device Tree
-
-Juno's device tree blob is built along with the kernel. It is located in:
-
-    <path-to-linux>/arch/arm64/boot/dts/arm/juno.dtb
+After building Trusted Firmware, the files `bl1.bin` and `fip.bin` need copying
+to the `SOFTWARE/` directory as explained in the [Juno Software Guide].
