From 67c2829b646bb5b859088b36fbc89e971b9c1960 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Mon, 6 Oct 2008 04:42:33 -0400 Subject: Blackfin: support embedding the environment into loader files (LDRs) For the most part, the Blackfin processor boots files in the LDR format rather than binary/ELF files. So we want to export the environment as a raw blob to the LDR utility so it can embed it at the right location.
