From 237e3793fbe4227105dee586d95942c0ac3f6b62 Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Fri, 31 Oct 2014 08:31:05 +0100 Subject: arm, at91, spl: add spl support for the taurus board MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit replaces the at91bootstrap code with SPL code. make the spl image with: ./tools/mkimage -T atmelimage -d spl/u-boot-spl.bin spl/boot.bin this writes the length of the spl image into the 6th execption vector. This is needed from the ROM bootloader.
