From d2ea2bf740c515de41f45e4d6f36683db3458881 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Sun, 19 Jan 2014 17:47:43 +0100 Subject: PPC: Add L1CFG1 SPR emulation In addition to the L1 data cache configuration register L1CFG0 there is also another one for the L1 instruction cache called L1CFG1. Emulate that one with the same values as the data one.
