From b68346247f74e002ef180403167888a03f488080 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Fri, 24 May 2013 15:47:26 +0200 Subject: arm/early-printk: calculate baud rate divisor from user provided value For early-printk the used baud rate was hardcoded in the code, using precalculated divisor values. Let the calculation of these values be done by the preprocessor and use a human readable value in xen/arch/arm/Rules.mk to drive this.
