From 377656b2cc3be3e704fc574041669a4a84ea6bb8 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Tue, 14 Jun 2016 21:33:23 -0700 Subject: x86: baytrail: Introduce a Kconfig option for the internal UART There are quite a number of BayTrail boards that uses an external SuperIO chipset to provide the legacy UART. For such cases, it's better to have a Kconfig option to enable the internal UART. So far BayleyBay and MinnowMax boards are using internal UART as the U-Boot console, enable this on these two boards.
