there are some binary files required by mkimage-imx

1. DDR PHY firmware images (Mandatory, used for all targets)
Files: lpddr4_pmu_train_imem.bin and lpddr4_pmu_train_dmem.bin
Git: ssh://git@sw-stash.freescale.net/imx/linux-firmware-imx.git
Directory: firmware/ddr/synopsys

2. u-boot and SPL images (Mandatory, used for all targets)
Files: u-boot.bin and u-boot-spl.bin
Git: ssh://git@sw-stash.freescale.net/imx/uboot-imx.git
Directory: ./u-boot.bin and spl/u-boot-spl.bin
Build command: make imx8mq_evk_defconfig; make

3. ATF image (Mandatory, used for all targets)
File: bl31.bin
Git: ssh://git@sw-stash.freescale.net/imx/arm-trusted-firmware.git

Build command: make PLAT=imx8mq

4. HDMI firmware image (flash_hdmi_spl_uboot and flash_hdmi_spl_uboot_tee)

besides the 2&&3 which i can build from source. I can't find the other binary files (1/4/5).
