|
+ <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
|

+ 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
