From 21d29f7f9f4888a4858b58b368ae7cf8783a6ebf Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Wed, 28 May 2014 11:33:33 +0200 Subject: bootm: make use of legacy image format configurable make the use of legacy image format configurable through the config define CONFIG_IMAGE_FORMAT_LEGACY. When relying on signed FIT images with required signature check the legacy image format should be disabled. Therefore introduce this new define and enable legacy image format if CONFIG_FIT_SIGNATURE is not set. If CONFIG_FIT_SIGNATURE is set disable per default the legacy image format.
