+Subject: [PATCH 1/3] 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.
