From ce8eebd3b7642e3d675616fb8d3d068cb58d66ef Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Wed, 29 May 2019 18:33:35 +0200 Subject: soc/intel/common/uart: Only return valid UART base We only configure the base address for the console UART, the other addresses are never assigned to the hardware. It seems better to return 0 for them instead of a spurious value.
