After adding "earlycon" to the boot arguments, I get the log > below: [...] > [ 0.393618] uart-pl011 f7112000.uart: could not find pctldev for node /soc/pinmux@f7010000/uart2_pmx_func, deferring probe So we're missing the pinctrl driver, pinctrl-single. This commit in 4.7 added explicit pinmuxing for the UARTs: commit c2aad93200fa2dbbc6c48632e619494080d64796 Author: Guodong Xu <guod ong.xu@linaro.org> Date: Wed Apr 13 07:55:48 2016 +0800 arm64: dts: hi6220: add pinctrl for uarts and enable them Since the boot loader will always set up pinmuxing for the console UART you could get away without pinctrl-single before this. Anyway I've now enabled CONFIG_PINCTRL_SINGLE for arm64. Ben. -- Ben Hutchings Design a system any fool can use, and only a fool will want to use it.
