From b678f2790c8634539a3458f03d53f2273e0fdc75 Mon Sep 17 00:00:00 2001 From: Kever Yang Date: Mon, 22 Jul 2019 20:02:12 +0800 Subject: [PATCH] rockchip: rk3288: Move veyron_init() back to veyron.c The veyron_init() should go to its board file veyron.c, and the board_early_init_f() could be the right place.
