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