From a131c1f44231e3546b1cca8480400c98d1dd7ac8 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 30 Aug 2015 16:55:24 -0600 Subject: rockchip: Add the rkimage format to mkimage Rockchip SoCs require certain formats for code that they execute, The simplest format is a 4-byte header at the start of a binary file. Add support for this so that we can create images that the boot ROM understands.
