Subject: [U-Boot] [PATCH] Exynos5250: Remove lowlevelinit
Date: Fri, 14 Feb 2014 13:52:48 +0530 [thread overview]
Message-ID: <1392366168-20296-1-git-send-email-rajeshwari.s@samsung.com> (raw)
From: Rajeshwari S Shinde <rajeshwari.s@samsung.com>
Since we use CONFIG_SKIP_LOWLEVEL_INIT for Exynos baords, we dont need to a
lowlevel_init.S file.
