The script is basically the only required interface to the TI SECDEV
package for creating a bootable SPL image for secure TI devices.
+ Invoking the script for AM33xx Secure Devices
+ =============================================
+
+ create-boot-image.sh \
+ <IMAGE_FLAG> <INPUT_FILE> <OUTPUT_FILE> <SPL_LOAD_ADDR>
+
+ <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
+ <INPUT_FILE>
+
