From b39cacc268a3feb3b21a0b966e1c293ab5c96a40 Mon Sep 17 00:00:00 2001 From: Stefan Bosch Date: Fri, 10 Jul 2020 19:07:38 +0200 Subject: arm: add (default) config for nanopi2 board Changes in relation to FriendlyARM's U-Boot nanopi2-v2016.01: - Configuration changed, mainly several "CONFIG_..." moved from s5p4418_nanopi2.h to s5p4418_nanopi2_defconfig and USB related configs removed because USB is not supported yet. - s5p4418_nanopi2.h: "CONFIG_" removed from several s5p4418/nanopi2 specific defines because the appropriate values do not need to be configurable. - pinctrl is supported now, therefore "CONFIG_PINCTRL=y" added to s5p4418_nanopi2_defconfig.
