The following linker failure can be seen for a certain heavily reduced defconfig: drivers/soc/sunxi/sunxi_sram.o: In function `sunxi_sram_probe': drivers/soc/sunxi/sunxi_sram.c:353: undefined reference to `__devm_regmap_init_mmio_clk' drivers/soc/sunxi/sunxi_sram.c:353:(.text+0x3c4): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `__devm_regmap_init_mmio_clk'
It would seem that the sunxi sram driver implicitly depended on config REGMAP_MMIO. To solve, select config REGMAP_MMIO for ARCH_SUNXI. This seems a better option than selecting from the respective driver config as this just defaults to ARCH_SUNXI.
