From a749690ecf7ab55aa46df1698bcee3ec110612df Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Thu, 13 Jul 2006 17:52:01 +1000 Subject: [POWERPC] iseries: Use device tree /system-id in /proc/iSeries/config We export a bunch of info in /proc/iSeries/config. Currently we pull it directly out of some iSeries specific structs, but we could use the device tree instead, this saves decoding it twice and is a little neater.
