 * $Log$
 * Revision 1.5  2009/01/18 16:44:56  haraldkipp
 * Introduced target independent port numbers.
 * Distinguish between PIO IDs and port numbers.
 *
 * Revision 1.4  2009/01/18 10:45:54  haraldkipp
 * Fixed bit banging SPI for ARM targets.
 *
 * Revision 1.3  2008/08/28 16:11:31  haraldkipp
 * Fixed bitbanging SPI for ARM targets.
 *
 * Revision 1.2  2008/08/11 06:59:59  haraldkipp
 * BSD types replaced by stdint types (feature request #1282721).
 *
 * Revision 1.1  2007/04/12 09:07:54  haraldkipp
 * Configurable SPI added.
