From 83cdf6faa677ff8ff39d7852126aad3207fac021 Mon Sep 17 00:00:00 2001 From: Nikita Kiryanov Date: Sun, 8 Nov 2015 17:11:48 +0200 Subject: [PATCH] spl: mmc: get rid of emmc boot code duplication Get rid of emmc boot code duplication in spl_mmc_load_image() using a switch case fallthrough into MMCSD_MODE_RAW. Since the #ifdef CONFIG_SUPPORT_EMMC_BOOT check is not really necessary, remove it in the process. No functional changes.
