[PATCH] Versatile Express: add NO_IOPORT

Russell King - ARM Linux linux at arm.linux.org.uk
Sat Feb 4 05:50:13 EST 2012


On Versatile Express, the PCI Express buses are broken and unusable, so
we aren't going to support PCI/ISA IO cycles on this platform.  Remove
the PCI/ISA IO inb et.al. support for this platform.
