$ git clone https://github.com/ARM-software/arm-trusted-firmware.git
$ git checkout v2.5
$ make PLAT=imx8mq ARCH=aarch64 CROSS_COMPILE=aarch64-linux-gnu- bl31
$ cp build/imx8mq/release/bl31.bin $(builddir)

Get DDR and HDMI firmware

Note: builddir is U-Boot build directory (source directory for in-tree builds)

$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.11.bin
$ chmod +x firmware-imx-8.11.bin
$ ./firmware-imx-8.11
$ cp firmware-imx-8.11/firmware/ddr/synopsys/lpddr4*.bin $(builddir)
$ cp firmware-imx-8.11/firmware/hdmi/cadence/signed_hdmi_imx8m.bin $(builddir)

Build U-Boot

$ make kontron_pitx_imx8m_defconfig
$ make CROSS_COMPILE=aarch64-linux-gnu-
