/* * Load Image is completed in two stages: * * 1) When the VK device boot-up, M7 CPU runs and executes the BootROM. * The Secure Boot Loader (SBL) as part of the BootROM will run * to open up ITCM for host to push BOOT1 image. * SBL will authenticate the image before jumping to BOOT1 image. * * 2) Because BOOT1 image is a secured image, we also called it the * Secure Boot Image (SBI). At second stage, SBI will initialize DDR * and wait for host to push BOOT2 image to DDR. * SBI will authenticate the image before jumping to BOOT2 image. *
