From f8f9107d97b849afe69ca86e7abd8d1748ea7acd Mon Sep 17 00:00:00 2001 From: Teddy Reed Date: Thu, 9 Jun 2016 19:38:02 -0700 Subject: mkimage: fit: spl: Add an optional static offset for external data When building a FIT with external data (-E), U-Boot proper may require absolute positioning for executing the external firmware. To acheive this use the (-p) switch, which will replace the amended 'data-offset' with 'data-position' indicating the absolute position of external data. It is considered an error if the requested absolute position overlaps with the initial data required for the compact FIT.
