From 7f4392cdcc63fea72fc77d14497059267d77d5d0 Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Mon, 14 Apr 2008 02:52:38 +1000 Subject: [PATCH] [POWERPC] Efika: Really, don't pretend to be CHRP Fedora 9 works on Efika without the separate 'device-tree supplement', thanks to the kernel's own fixups. With one exception -- because 'CHRP' still appears on the 'machine:' line in /proc/cpuinfo, the installer misdetects the platform and misconfigures yaboot, putting it into a PReP boot partition instead of in the /boot filesystem where the Efika's firmware could find it. The kernel's fixups for Efika already correct one instance of 'chrp', in the 'device_type' property. This fixes it in the 'CODEGEN,description' property too, since that's what's exposed to userspace in /proc/cpuinfo.
