From 22aa21dba4085bb8d597eeeeeee9e3328af684bb Mon Sep 17 00:00:00 2001 From: Niko Mauno Date: Thu, 3 Aug 2017 09:53:24 +0300 Subject: [PATCH] splash_source: Verify FIT magic Before reading entire FIT image, add sanity check by testing image header against FDT_MAGIC. This should help avoid problems in situations where FIT is not yet available from storage device, for example when performing initial programming of device.
