        package for creating a bootable SPL image for secure TI devices.

+
+       <IMAGE_FLAG> is a value that specifies the type of the image to
+       generate OR the action the image generation tool will take. Valid
+       values are:
+               SPI_X-LOADER - Generates an image for SPI flash (byte swapped)
+               X-LOADER - Generates an image for non-XIP flash
+               MLO - Generates an image for SD/MMC/eMMC media
+               2ND - Generates an image for USB, UART and Ethernet
+               XIP_X-LOADER - Generates a single stage u-boot for NOR/QSPI XiP
+
+       <INPUT_FILE> is the full path and filename of the public world boot
+       loaderbinary file (depending on the boot media, this is usually
+       either u-boot-spl.bin or u-boot.bin).
+
+       <OUTPUT_FILE> is the full path and filename of the final secure
+       image. The output binary images should be used in place of the standard
+       non-secure binary images (see the platform-specific user's guides and
+       releases notes for how the non-secure images are typically used)
+       u-boot-spl_HS_SPI_X-LOADER - byte swapped boot image for SPI flash
+       u-boot-spl_HS_X-LOADER - boot image for NAND or SD/MMC/eMMC rawmode
+       u-boot-spl_HS_MLO - boot image for SD/MMC/eMMC media
+       u-boot-spl_HS_2ND - boot image for USB, UART and Ethernet
+       u-boot_HS_XIP_X-LOADER - boot image for NOR or QSPI Xip flash
+
+       <SPL_LOAD_ADDR> is the address at which SOC ROM should load the
