From 60570df19c7e7bc9f1f10d228bfe1ac2bea52d9b Mon Sep 17 00:00:00 2001 From: kunhuahuang Date: Tue, 28 Apr 2015 03:01:19 +0800 Subject: stm32f4: add serial print port Add the stm32F4 board's serial ports support. User can use it easily. The user only need to edit the number of the usart. The patch also fix the serial print out. Last, this version of patch fix the first patch checkpatch.pl error. Thanks to Kamil Lulko.
