From: Andre Przywara Date: Tue, 13 Aug 2013 15:12:52 +0000 (+0200) Subject: PL011: don't force baud rate of 38400 bps X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~6521 X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=db58a28b9b41722aee7c812d6621360c88317049;p=xen.git 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.
