From afa7b13b9355b3df3da7606d434cb8b450316ab9 Mon Sep 17 00:00:00 2001 From: Kyösti Mälkki Date: Thu, 13 Feb 2014 17:16:22 +0200 Subject: uart: Redefine Kconfig options MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Option DRIVERS_UART builds with support for UART hardware. Option CONSOLE_SERIAL enables the console output for UART. Those x86 boards that do not have serial port on SuperIO should select NO_UART_ON_SUPERIO to disable 8250 UART for the default configuration.
