From 4c81acab3816c6941900c2abdb412df6cf34bc74 Mon Sep 17 00:00:00 2001 From: Rafał Miłecki Date: Fri, 22 Jan 2016 18:02:54 +0100 Subject: bcma: init serial console directly from ChipCommon code MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit UART is connected to and controlled over ChipCommon core. It doesn't have much to do with MIPS core (where we initialize it currently) except just existing on embedded systemms. There isn't point of such cross-core initialization (and we needed #ifdef anyway) so just handle it in ChipCommon.
