mn10300: add io{read,write}{16,32}be functions
These functions are used in various drivers, including the latest version of the 8250 driver. The latter causes the following build failure. drivers/tty/serial/8250/8250_core.c: In function 'mem32be_serial_out': drivers/tty/serial/8250/8250_core.c:456:2: error: implicit declaration of function 'iowrite32be' drivers/tty/serial/8250/8250_core.c: In function 'mem32be_serial_in': drivers/tty/serial/8250/8250_core.c:462:2: error: implicit declaration of function 'ioread32be' Cc: Kevin Cernekee <cernekee@gmail.com> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Fixes: c627f2ceb692 ("serial: 8250: Add support for big-endian MMIO accesses") Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Rob Herring <robh@kernel.org>
