Get and Build the ARM Trusted firmware

$ git clone https://github.com/nxp-imx/imx-atf.git -b lf_v2.4
$ make PLAT=imx8mp bl31 CROSS_COMPILE=aarch64-linux-gnu-
$ cp build/imx8mp/release/bl31.bin .

Get the DDR Firmware

$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.9.bin
$ chmod +x firmware-imx-8.9.bin
$ ./firmware-imx-8.9.bin
$ cp firmware-imx-8.9/firmware/ddr/synopsys/lpddr4*.bin .

Build U-Boot

$ make imx8mp_venice_defconfig
$ make CROSS_COMPILE=aarch64-linux-gnu-

Update eMMC

=> tftpboot $loadaddr flash.bin
=> setexpr blkcnt $filesize + 0x1ff && setexpr blkcnt $blkcnt / 0x200
=> mmc dev 2 0 && mmc write $loadaddr 0x40 $blkcnt # emmc user hw part
=> mmc dev 2 1 && mmc write $loadaddr 0 $blkcnt # or emmc boot0 hw part
=> mmc dev 2 2 && mmc write $loadaddr 0 $blkcnt # or emmc boot1 hw part
