From 0662946aa6d3129e7974d4484fc94ab2a5b15d4e Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Thu, 3 May 2018 21:24:39 +0100 Subject: uninorth: create new uninorth device MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit 4e46dcdbd3 "PPC: Newworld: Add uninorth token register" added a TODO which was to convert the uninorth registers hack to a proper device. Move these registers to a new uninorth device, removing the old hacks from mac_newworld.c.
