From 540270d82db943855538cea5d0c790e7e669dda0 Mon Sep 17 00:00:00 2001 From: Geoff Levand Date: Mon, 19 Jun 2006 20:33:29 +0200 Subject: [POWERPC] spufs: further abstract priv1 register access To support muti-platform binaries the spu hypervisor accessor routines must have runtime binding. I removed the existing statically linked routines in spu.h and spu_priv1_mmio.c and created new accessor routines in spu_priv1.h that operate indirectly through an ops struct spu_priv1_ops. spu_priv1_mmio.c contains the instance of the accessor routines for running on raw hardware.
