From 6cb83829a013ed2631cba5d5c9bf42eaf2380131 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Thu, 25 Apr 2013 10:16:02 +0000 Subject: [PATCH] tools: arm: imx: Implement BOOT_OFFSET command for imximage MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Implement BOOT_OFFSET command for imximage. This command is parallel to current BOOT_FROM command, but allows more flexibility in configuring arbitrary image header offset. Also add an imximage.cfg with default offset values into arm/arch/imx-common/ so the board-specific imximage.cfg can include this file to avoid magic constants. The syntax of BOOT_OFFSET command is "BOOT_OFFSET ".
