From 648e87a1ec961de00ac0d7dcbd15b2ff1804ef8d Mon Sep 17 00:00:00 2001 From: David Lechner Date: Sat, 19 May 2018 23:25:04 -0500 Subject: [PATCH] ARM: legoev3: Move UART enable to early init This moves the UART init for LEGO MINDSTORMS EV3 to board_early_init_f(). Some console messages were not being printed because the UART was not enabled until later in the init process.
