Boot Flow in secure systems: 1. User loads the u-boot image in flash 2. PBL/Configuration word is used to create LAW for Flash at 0xc0000000 (Please note that ISBC expects all these addresses, images to be validated, entry point etc within 0 - 3.5G range) 3. On system reset, BOOt ROM code executes first. It validates the u-boot image, and then passes control to u-boot
The patch set adds the changes for u-boot to execute after BOOT ROM code in secure systems.
