From edf18a83f8dc993279947cfc7faaba7dedf1ad82 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 28 Feb 2019 17:19:54 +0200 Subject: [PATCH] x86: acpi: Not every platform has serial console a first device We may not do an assumption that current console device is always a first of UCLASS_SERIAL one. For example, on properly described Intel Edison board the console UART is a third one. Use current serial device as described in global data.
