Update user guide to use Linaro releases 

Linaro produce monthly software releases for the Juno and AEMv8-FVP
platforms. These provide an integrated set of software components
that have been tested together on these platforms.

From now on, it is recommend that Trusted Firmware developers use the
Linaro releases (currently 15.06) as a baseline for the dependent
software components: normal world firmware, Linux kernel and device
tree, file system as well as any additional micro-controller firmware
required by the platform.

This patch updates the user guide to document this new process. It
changes the instructions to get the source code of the full software
stack (including Trusted Firmware) and updates the dependency build
instructions to make use of the build scripts that the Linaro releases
provide.

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
To build the Trusted Firmware images, follow these steps: # 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
1. Clone the ARM Trusted Firmware repository from GitHub:
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 git clone https://github.com/ARM-software/arm-trusted-firmware.git
2. Change to the trusted firmware directory: However, the rest of this document assumes that you got the Trusted Firmware
as part of the Linaro release.

--------------------------------------- -------------------------------------------
### Obtaining EDK2
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.
To build the software to be compatible with the Foundation and Base FVPs, or the The Linaro release provides a set of scripts that automate the process of
Juno platform, follow these steps: 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.
1. Clone the [EDK2 source code][EDK2] from GitHub: The instructions below are targeted at an OpenEmbedded filesystem.
git clone -n https://github.com/tianocore/edk2.git 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:
Not all required features are available in the EDK2 mainline yet. These can # Disable ARM Trusted Firmware build
be obtained from the ARM-software EDK2 repository instead: ARM_TF_BUILD_ENABLED=0
cd edk2 2. Launch the build script:
git remote add -f --tags arm-software https://github.com/ARM-software/edk2.git
git checkout --detach v3.0
2. Copy build config templates to local workspace CROSS_COMPILE=aarch64-linux-gnu- \
build-scripts/build-all.sh <platform>-oe
# in edk2/ ### Preparing the Firmware Image Package
. edksetup.sh
3. Build the EDK2 host tools 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:
make -C BaseTools clean uefi/edk2/Build/ArmVExpress-FVP-AArch64-Minimal/DEBUG_GCC49/FV/FVP_AARCH64_EFI.fd [for FVP]
make -C BaseTools uefi/edk2/Build/ArmJuno/DEBUG_GCC49/FV/BL33_AP_UEFI.fd [for Juno]
4. Build the EDK2 software ### Building an alternative EDK2
1. Build for FVP * By default, EDK2 is built in debug mode. To build a release version instead,
change the following line in the variant file:
GCC49_AARCH64_PREFIX=<absolute-path-to-aarch64-gcc>/bin/aarch64-none-elf- \ UEFI_BUILD_MODE=DEBUG
make -f ArmPlatformPkg/Scripts/Makefile EDK2_ARCH=AARCH64 \
EDK2_DSC=ArmPlatformPkg/ArmVExpressPkg/ArmVExpress-FVP-AArch64.dsc \
EDK2_TOOLCHAIN=GCC49 EDK2_BUILD=RELEASE \
EDK2_MACROS="-n 6 -D ARM_FOUNDATION_FVP=1"
The EDK2 binary for use with the ARM Trusted Firmware can then be found into:
here:
Build/ArmVExpress-FVP-AArch64/RELEASE_GCC49/FV/FVP_AARCH64_EFI.fd UEFI_BUILD_MODE=RELEASE
2. Build for Juno * 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:
GCC49_AARCH64_PREFIX=<absolute-path-to-aarch64-gcc>/bin/aarch64-none-elf- \ build-scripts/build-uefi.sh fvp-oe clean
make -f ArmPlatformPkg/ArmJunoPkg/Makefile EDK2_ARCH=AARCH64 \
EDK2_TOOLCHAIN=GCC49 EDK2_BUILD=RELEASE
The EDK2 binary for use with the ARM Trusted Firmware can then be found Then edit the following file:
here:
Build/ArmJuno/RELEASE_GCC49/FV/BL33_AP_UEFI.fd uefi/edk2/ArmPlatformPkg/ArmVExpressPkg/ArmVExpress-FVP-AArch64.mak
The EDK2 binary should be specified as `BL33` in in the `make` command line and add the following build flag into the `EDK2_MACROS` variable:
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:
-D ARM_FVP_LEGACY_GICV2_LOCATION=1 -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 Finally rebuild the Trusted Firmware to generate a new FIP using the
instructions in the "Building the Trusted Firmware" section. instructions in the "Building the Trusted Firmware" section.
### Obtaining a Linux kernel 7. Preparing the images to run on FVP
Preparing a Linux kernel for use on the FVPs can be done as follows
(GICv2 support only):
1. Clone Linux:
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
2. Build with the Linaro GCC tools.
# in linux/
make mrproper
make ARCH=arm64 defconfig
CROSS_COMPILE=<path-to-aarch64-gcc>/bin/aarch64-none-elf- \
make -j6 ARCH=arm64
The compiled Linux image will now be found at `arch/arm64/boot/Image`.

### 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 8. Running the software on FVP
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 .
sudo sh -c "echo 'devtmpfs /dev devtmpfs mode=0755,nosuid 0 0' >> etc/fstab"
sudo sh -c "find . | cpio --quiet -H newc -o | gzip -3 -n > ../filesystem.cpio.gz"
cd ..
3. Copy the resultant `filesystem.cpio.gz` to the directory where the FVP is
launched from. Alternatively a symbolic link may be used.

### Preparing Trusted Firmware images This version of the ARM Trusted Firmware has been tested on Juno r0 and Juno r1.
To execute the versions of software components on Juno referred to in this 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 document, the latest Juno board recovery image must be installed. If you
have an earlier version installed or are unsure which version is installed, have an earlier version installed or are unsure which version is installed,
follow the recovery image update instructions in the [Juno Software Guide] follow the recovery image update instructions in the [Juno Software Guide]
on the [ARM Connected Community] website. on the [ARM Connected Community] website. The latest Juno board recovery image
can be obtained from [Linaro releases], see section 2.7 "Using prebuilt
binaries".
Note that you must use the board recovery image provided in the Juno R1 Initial ### Preparing Trusted Firmware images
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), 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 whereas the BL30 image contains the SCP Runtime firmware. Both images are
embedded within the [Juno Board Recovery Image] but they can also be downloaded embedded within the Juno board recovery image, these are the files `bl0.bin`
directly: [Juno SCP ROM Firmware] and [Juno SCP Runtime Firmware]. 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:
fip_create --dump --bl30 <path-to>/<bl30-binary> <path-to>/<FIP-binary> 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".
### Obtaining the Flattened Device Tree After building Trusted Firmware, the files `bl1.bin` and `fip.bin` need copying
to the `SOFTWARE/` directory as explained in the [Juno Software Guide].
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
