+SolidRun MacchiatoBin
+=====================
+
+# Summary
+
+This is a port of 64-bit TianoCore EDK II firmware for the SolidRun MacchiatoBin platform based on the Marvell ARMADA 8040 SoC.
+
+# Building the firmware
+
+## Prepare toolchain (for cross-compilation only):
+
+1. Download the toolchain:
+
+   ```
+   wget https://releases.linaro.org/components/toolchain/binaries/7.5-2019.12/aarch64-linux-gnu/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.tar.xz
+   ```
+
+1. After extracting, setup the path and compiler prefix to GCC5\_AARCH64\_PREFIX variable:
+
+   ```
+   export GCC5_AARCH64_PREFIX=<toolchain_path>/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-
+   ```
+
+## Prepare prerequisites
+
+1. Create a new folder (directory) on your local development machine
+   for use as your workspace. This example uses `/work/git/tianocore`, modify as
+   appropriate for your needs.
+
+   ```
+   $ export WORKSPACE=/work/git/tianocore
+   $ mkdir -p $WORKSPACE
+   $ cd $WORKSPACE
+   ```
+
+1. Clone the Trusted Firmware repository:
+
+   ```
+   $ cd ${WORKSPACE}
+   $ git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
+   ```
+1. Clone repository for auxiliary firmware on the SoC co-processors and checkout to binaries-marvell-armada-SDK10.0.1.0:
+
+   ```
+   $ cd ${WORKSPACE}
+   $ git clone https://github.com/MarvellEmbeddedProcessors/binaries-marvell.git
+   $ cd binaries-marvell/
+   $ git checkout -b binaries-marvell-armada-SDK10.0.1.0 origin/binaries-marvell-armada-SDK10.0.1.0
+   ```
+1. Clone the DDR training code from:
+
+   ```
+   $ cd ${WORKSPACE}
+   $ git clone https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git
+   ```
+## Prepare EDKII environment:
+
+Please follow instructions from "Obtaining source code" and "Manual building" from the top level edk2-platforms [Readme.md](https://github.com/tianocore/edk2-platforms#readme).
+
+## Build EDKII:
+
+1. Use below build command:
+
+   ```
+   $ cd ${WORKSPACE}
+   $ build -a AARCH64 -t GCC5 -b RELEASE -D INCLUDE_TFTP_COMMAND -D X64EMU_ENABLE -p Platform/SolidRun/Armada80x0McBin/Armada80x0McBin.dsc
+   ```
+
+## Build the final firmware image:
+
+1. Set BL33 variable to path to EDK II output binary:
+
+   ```
+   $ export BL33=${WORKSPACE}/Build/Armada80x0McBin-AARCH64/RELEASE_GCC5/FV/ARMADA_EFI.fd
+   ```
+1. Export SCP_BL2 variable:
+
+   ```
+   $ export SCP_BL2=${WORKSKPACE}/binaries-marvell/mrvl_scp_bl2.img
+   ```
+1. Export compiler variables (for cross-compilation only):
+
+   ```
+   $ export ARCH=arm64
+   $ export CROSS_COMPILE=<toolchain_path>/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-
+   ```
+1. Build the image:
+
+   ```
+   $ cd ${WORKSPACE}/trusted-firmware-a/
+   $ make LOG_LEVEL=20 MV_DDR_PATH=${WORKSPACE}/mv-ddr-marvell PLAT=a80x0_mcbin all fip mrvl_flash
+   ```
+The firmware image `flash-image.bin` can be found in `build/a80x0_mcbin/release/` directory.
+
+# ARM System Ready certification.
+
+MacchiatoBin is [System Ready ES](https://developer.arm.com/architectures/system-architectures/arm-systemready/es) certified. Release binary and the firmware components' baselines list are available in a dedicated [wiki page](https://github.com/semihalf/edk2-platforms/wiki).
