From c7fefcb9125bbd183dc095996c6747273043d988 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 18 Oct 2015 19:51:25 -0600 Subject: debug_uart: Add an option to announce the debug UART It is useful to see a message from the debug UART early during boot so that you know things are working. Add an option to enable this. The message will be displayed as soon as debug_uart_init() is called.
