From 94b212c29f685ca54b5689a8e89ac7671c43d651 Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Wed, 16 Nov 2005 13:38:21 +1100 Subject: powerpc: Move ppc64 boot wrapper code over to arch/powerpc This also extends the code to handle 32-bit ELF vmlinux files as well as 64-bit ones. This is sufficient for booting on new-world 32-bit powermacs (i.e. all recent machines).
