From 74025300d55262155a3bdafddf257d82dcf0f6af Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Fri, 24 May 2013 15:47:28 +0200 Subject: arm/early-printk: move UART base address to Rules.mk The UART memory mapped base address is currently hardcoded in the early-printk UART driver, which denies the driver to be used by two machines with a different mapping. Move this definition out to xen/arch/arm/Rules.mk, allowing easier user access and later sharing of the driver.
