From e4c444b34b6ff6b347e552805ee89c48f85785bb Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Fri, 28 Jun 2013 14:43:01 -0400 Subject: [PATCH] spl_mmc.c: Detect missing kernel image in RAW MMC Currently, we assume that if we can read from MMC correctly, we have found a valid image. This is not the case as an empty area will read just fine. Add a check for a valid IH_MAGIC.
