From 445614cc2fbbbdb2be32663b7ba0927ac99cb353 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Wed, 27 May 2015 13:24:10 -0400 Subject: [PATCH] Revert "Revert "stm32f4: fix serial output"" Due to a misunderstanding, in 698a12b we reverted changes that we in fact wanted to keep. So lets fix that mistake and bring the code back to how it should have been. This reverts commit 698a12bef9e782dcd99c555a739c16eec8669f14.
