From 429fa25e171a35a74e7676acb45f3f706a038722 Mon Sep 17 00:00:00 2001 From: Eugeniy Paltsev Date: Thu, 3 May 2018 15:01:58 +0300 Subject: [PATCH] ARC: init debug uart in early common arc code The debug UART is intended for use very early in U-Boot to debug problems before serial drivers are up. Call debug_uart_init right before board_init_f.
