Build Guide

imx-mkimage is used to combine input images and generate final boot image with appropriate IVT set. 
Before building the boot image, need to prepare the input images first:

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
   Directory:		build/imx8mq/release
   Build command:	make PLAT=imx8mq
  
4. HDMI firmware image (flash_hdmi_spl_uboot and flash_hdmi_spl_uboot_tee)
   File:		hdmi_imx8m.bin
   Git:			ssh://git@sw-stash.freescale.net/imx/linux-firmware-imx.git
   Directory:		firmware/hdmi/cadence
   
5. Optee image (flash_hdmi_spl_uboot_tee and flash_spl_uboot_tee)
   File:		tee.bin
   Git:			ssh://git@sw-stash.freescale.net/imx/imx-optee-os.git
