 * The EBSA110 has a weird "ISA IO" region:

 * --------------------------------------------------------
 * Physical region	IO region
 * f0000fe0 - f0000ffc	3f8 - 3ff  ttyS0

 * f0000be0 - f0000bfc	2f8 - 2ff  ttyS1
 *
 * Region 1 (addr = 0xf0000000 + (io & ~1) << 1 + (io & 1))
 * --------------------------------------------------------
 * Physical region	IO region
 * f00014f1             a79        pnp write data
 * f00007c0 - f00007c1	3e0 - 3e1  pcmcia
