Mangled by Mozilla below. This is a 7400 board with a memory mapped
uart. It is important to zero out the entries for serial ports that
aren't present, otherwise the serial driver will attempt to use the
traditional locations.



static void __init
tpe3_setup_arch(void)
{
	struct serial_struct req;

	...

	memset(&req, 0, sizeof (req));
	req.line = 0;
	req.io_type = SERIAL_IO_MEM;
	req.iomem_base = (void *) (tpe3_uart_base + 0x10);
	req.baud_base = 6144000 / 16;
	req.irq = 3;
	req.flags = ASYNC_BOOT_AUTOCONF | ASYNC_SKIP_TEST;
	early_serial_setup(&req);
	memset(&req, 0, sizeof (req));
	req.line = 1;
	early_serial_setup(&req);
	req.line = 2;
	early_serial_setup(&req);
	req.line = 3;
	early_serial_setup(&req);

	...
}
