Subject: [RFC PATCH v2 01/14] ARM: add CONFIG_ARCH_SUNXI_V7 for differentiate ARMv5/v7 Allwinner SoCs
Date:   Sun, 18 Nov 2018 17:17:00 +0300
Message-Id: <abbb75165c8ef41da6963d72f4155ad6ae79140c.1542546735.git.mesihkilinc@gmail.com>
In-Reply-To: <cover.1542546735.git.mesihkilinc@gmail.com>
References: <cover.1542546735.git.mesihkilinc@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Allwinner also has some ARMv5 SoCs.

In order to add support for them, add a CONFIG_ARCH_SUNXI_V7 bool config
which is selected when a ARMv7 soc is selected, and make CONFIG_ARCH_SUNXI
a common option which is selected by both V7 and V5 sunxi option.
