-## Prerequisites
-It is up to developer to setup arm64 build environment:
-* Download the [GNU tool chain](https://github.com/compulab-yokneam/meta-bsp-imx8mm/blob/iot-gate-imx8_r3.2/Documentation/toolchain.md)
-* Set environment variables:
-<pre>
-export ARCH=arm64
-export CROSS_COMPILE=/opt/gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu-
-</pre>
-* Create a folder to organize the files:
-<pre>
-mkdir -p imx8mm/{sources,results}
-export SRC_ROOT=$(readlink -f imx8mm/sources)
-export RESULTS=$(readlink -f imx8mm/results)
-cd ${SRC_ROOT}
-</pre>
-
-* Download CompuLab BSP
-<pre>
-git clone -b ${CPL_RELEASE} https://github.com/compulab-yokneam/meta-bsp-imx8mm.git
-export LAYER_DIR=$(pwd)/meta-bsp-imx8mm
-</pre>
-
-## Build Procedure
-### Firmware iMX setup
-* Download the firmware-imx file:
-<pre>
-wget http://www.freescale.com/lgfiles/NMG/MAD/YOCTO/${NXP_FIRMWARE}
-bash -x ${NXP_FIRMWARE} --auto-accept
-cp -v $(find firmware* | awk '/train|hdmi_imx8|dp_imx8/' ORS=" ") ${RESULTS}
-</pre>
-
-### Arm Trusted Firmware (ATF) setup
-* Download the ATF:
-<pre>
-git clone https://github.com/nxp-imx/imx-atf.git
-git -C imx-atf checkout ${ATF} -b ${CPL_BRANCH}
-</pre>
-* Apply patches if applicable:
-<pre>
-[[ -d ${LAYER_DIR}/recipes-bsp/imx-atf/compulab/imx8mm ]] && { \
-git -C imx-atf am ${LAYER_DIR}/recipes-bsp/imx-atf/compulab/imx8mm/*.patch
-}
-</pre>
-* Make bl31.bin
-
-|Mode |Command
-|---|---|
-|optee build|make -j 16 -C imx-atf PLAT=imx8mm BUILD_BASE=build PLAT=imx8mm IMX_BOOT_UART_BASE=0x30880000 BL32_BASE=0x56000000 BL32_SIZE=0x2000000 SPD=opteed bl31
-|non-optee build|make -j 16 -C imx-atf PLAT=imx8mm BUILD_BASE=build PLAT=imx8mm IMX_BOOT_UART_BASE=0x30880000 BL32_BASE=0x56000000 BL32_SIZE=0x2000000 bl31
-
-* Ceate a symlink in the ${RESULTS} folder:
-<pre>
-ln -s $(readlink -f imx-atf/build/imx8mm/release/bl31.bin) ${RESULTS}/
-</pre>
-
-### OP-TEE Setup
-
-| Skip this for a non-optee build |
-| --- |
-
-* Download the OP-TEE:
-<pre>
-git clone https://github.com/nxp-imx/imx-optee-os
-git -C imx-optee-os checkout ${OPTEE} -b ${CPL_BRANCH}
-</pre>
-* Apply patches if applicable:
-<pre>
-[[ -d ${LAYER_DIR}/recipes-security/optee-imx/compulab/imx8mm ]] && { \
-git -C imx-optee-os am ${LAYER_DIR}/recipes-security/optee-imx/compulab/imx8mm/*.patch
-}
-</pre>
-* Set environment variables:
-<pre>
-export ARCH=arm
-export CROSS_COMPILE64=${CROSS_COMPILE}
-</pre>
-* Make tee.bin
-<pre>
-make -j 16 -C imx-optee-os PLATFORM=imx PLATFORM_FLAVOR=mx8mm_cl_iot_gate
-ln -s $(readlink -f imx-optee-os/out/arm-plat-imx/core/tee-raw.bin) ${RESULTS}/tee.bin
-</pre>
-
-### U-Boot
-* Download the U-Boot source and apply CompuLab BSP patches:
-<pre>
-git clone https://github.com/nxp-imx/uboot-imx.git
-git -C uboot-imx checkout ${UBOOT} -b ${CPL_BRANCH}
-git -C uboot-imx am ${LAYER_DIR}/recipes-bsp/u-boot/compulab/imx8mm/*.patch
-</pre>
-* Restore `ARCH` environment variables:
-<pre>
-export ARCH=arm64
-</pre>
-* Compile U-Boot flash.bin:
-<pre>
-make -j 16 -C uboot-imx O=${RESULTS} -f defconfig.mk
-make -j 16 -C uboot-imx O=${RESULTS}
-</pre>
-
-## Flashing
-<pre>
-dd if=${RESULTS}/flash.bin of=/dev/<your device> bs=1K seek=33 status=progress
-</pre>
