From fd6e7d2d6a0231ebfa08e1f9a323497ea548da7d Mon Sep 17 00:00:00 2001 From: "s.hauer@pengutronix.de" Date: Thu, 2 Nov 2006 13:56:10 +0100 Subject: [PATCH] Clean up usage of boot_dev dev_t boot_dev is declared in arch/powerpc/kernel/setup_32.c and in arch/powerpc/kernel/setup_64.c but not used in these files. It is only used in arch/powerpc/platforms/powermac/setup.c, so make it static in this file.

Specifically, we look at the cpu-version property in the cpu node(s). If that contains a "logical" PVR value (of the form 0x0f00000x), we call identify_cpu again with this PVR value. A value of 0x0f000001 indicates the partition is in POWER5+ compatibility mode, and a value of 0x0f000002 indicates "POWER6 architected" mode, with various extensions disabled. We also look for various other properties: ibm,dfp, ibm,purr and ibm,spurr.
