From 1a71c5d158529bcfdadb131714710efb7679f529 Mon Sep 17 00:00:00 2001 From: Fabiano Rosas Date: Fri, 18 Feb 2022 08:34:14 +0100 Subject: [PATCH] target/ppc: cpu_init: Decouple G2 SPR registration from 755 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We're considering these two to be in different CPU families (6xx and 7xx), so keep their SPR registration separate. The code was copied into register_G2_sprs and the common function was renamed to apply only to the 755.
