From bef6229f36c1c2ddae186f4e328c2359c1dad18d Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Tue, 9 Jun 2015 19:38:04 +0200 Subject: [PATCH 1/5] ARM: sunxi: Add R8 support The R8 is a new Allwinner SoC based on the A13. While both are very similar, there's still a few differences. Introduce a new compatible to deal with them. In order to have a consistent naming, instead of mentioning the Allwinner A series as the machine name, switch to sun4i/sun5i like what is done for the other families.
