From 1c22753996fc7884115e478249b3080fb4bb9c83 Mon Sep 17 00:00:00 2001 From: Michael Niewöhner Date: Mon, 21 Dec 2020 03:46:58 +0100 Subject: mb/google/octopus: do UART pad configuration at board-level MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit UART pad configuration should not be done in common code, because that may cause short circuits, when the user sets a wrong UART index. Thus, add the corresponding pads to the early UART gpio table for the board as a first step. Common UART pad config code then gets dropped in CB:48829. Also switch to `bootblock_mainboard_early_init` to configure the pads in early bootblock before console initialization, to make the console work as early as possible. The board does not do any other gpio configuration in bootblock, so this should not influence behaviour in a negative way (e.g. breaking overrides).
