From 26dc0017d2b3a786b3ee9ac4fd24cdae1ae83896 Mon Sep 17 00:00:00 2001 From: Andreas Sandberg Date: Wed, 10 Aug 2016 15:27:13 +0100 Subject: ruby: Implement support for functional accesses to PIO ranges There are cases where we want to put boot ROMs on the PIO bus. Ruby currently doesn't support functional accesses to such memories since functional accesses are always assumed to go to physical memory. Add the required support for routing functional accesses to the PIO bus.
