From db58a28b9b41722aee7c812d6621360c88317049 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Tue, 13 Aug 2013 17:12:52 +0200 Subject: PL011: don't force baud rate of 38400 bps The PL011 driver currently sets the baudrate to a hardcoded value of 38400 bits/second. This will break Calxeda Midway, which uses 115200 bps. Instead don't tinker with the baud rate register at all and rely on the firmware or bootloader setting the correct value in here. This works fine on Versatile Express and Calxeda Midway.
