arm port, arm/allwinner sunxi soc support, the rest · Maintainers:
Russell King, Chen-Yu Tsai, Jernej Skrabec, Samuel Holland, Linus Torvalds
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.
