From 19dbc76228899be555b84a09fd3a364c2ce86bbb Mon Sep 17 00:00:00 2001 From: Noam Camus Date: Tue, 8 Nov 2016 15:20:59 +0200 Subject: ARC: [plat-eznps] set default baud for early console For CONFIG_SERIAL_EARLYCON we need 800MHz for NPS SoC The early console driver uses BASE_BAUD and not using dtb. The default of 50MHz is NOT good for NPS SoC.
