From fb5166ce35de489c8a96f3696e208eaae6a5a8d8 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Sat, 7 May 2011 17:55:04 -0400 Subject: Blackfin: add init.elf helper code This creates a standalone ELF that executes just the Blackfin initcode. This is useful for people who want to program the low level aspects of the CPU (memory/clocks/etc...) and can easily be used with JTAG for quick booting while developing.
