Subject: [PATCH 01/23] ARM: exynos: introduce EXYNOS_ATAGS symbol
Date: Tue,  5 Mar 2013 18:42:11 +0100
Message-ID: <1362505353-8873-2-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1362505353-8873-1-git-send-email-arnd@arndb.de>

As a preparation for multiplatform support, this introduces
a new Kconfig symbol to split the ATAGS based EXYNOS platforms
from the DT based ones. Turning off CONFIG_EXYNOS_ATAGS disables
all platforms that are not yet converted to DT, and we can
have code that relies on DT checking for this symbol being
disabled.
