[PATCH] powerpc/cell: disable legacy i/o area
We currently crash in the fedora installer because the keyboard driver tries to access I/O space that is not there on our hardware. This uses the same solution as powermac by just marking all legacy i/o as invalid. Signed-off-by: Arnd Bergmann <arndb@de.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
