From 3825ac0ee66b50cb0208ee74796fe65f3040e67c Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Tue, 8 Nov 2005 22:48:08 +1100 Subject: [PATCH] powerpc: Fix crash in early boot on some powermacs Some powermac machines were crashing in the quiesce firmware call in prom_init.c because we have just closed the OF stdin device; notably my 1999 G3 powerbook does this. To avoid this, don't close the OF stdin device on powermacs.
