From 892c587f22fc97362a595d3c84669a39ce1cd2f5 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Thu, 19 Apr 2012 15:34:06 +0200 Subject: [PATCH] PPC: Fix up e500 cache size setting When initializing the e500 code, we need to expose its cache line size for user and system mode, while the mmu details are only interesting for system emulation. Split the 2 switch statements apart, allowing us to #ifdef out the mmu parts for user mode emulation while keeping all cache information consistent.
