274 <title>ISA legacy functions</title>
275 <para>
276 On older kernels (2.2 and earlier) the ISA bus could be read or
277 written with these functions and without ioremap being used. This is
278 no longer true in Linux 2.4. A set of equivalent functions exist for
279 easy legacy driver porting. The functions available are prefixed
280 with 'isa_' and are <function>isa_readb</function>,
281 <function>isa_writeb</function>, <function>isa_readw</function>,
282 <function>isa_writew</function>, <function>isa_readl</function>,
283 <function>isa_writel</function>, <function>isa_memcpy_fromio</function>
284 and <function>isa_memcpy_toio</function>
285 </para>
286 <para>
287 These functions should not be used in new drivers, and will
288 eventually be going away.
