 	The script is basically the only required interface to the TI SECDEV
 	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
