From dda12e9a6f6ffcfac2642c11a1afb27af877e2c9 Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Wed, 28 Feb 2018 20:32:41 +0000 Subject: [PATCH] mac_newworld: use object link to pass OpenPIC object to macio Also switch macio_newworld_realize() over to use it rather than using the pic_mem memory region directly. Now that both Old World and New World macio devices no longer make use of the pic_mem memory region directly, we can remove it.
