The script is basically the only required interface to the TI SECDEV
package for creating a bootable SPL image for secure TI 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
