This patch adds support for the PCI-8604PW card equipped with four 878A. It is unknown who the manufacturer of this card is and no drivers were available during development of the patch. According to images found online, the card is originally sold with Linux DVR software. A CPLD on the card prevents the 878A from requesting access to the bus until an initialization sequence has been issued via GPIOs. The implemented sequence uses the minimum number of GPIOs needed to successfully unlock bus access. As there are many more GPIOs connected to the CPLD, it is very likely that some of the others have an influence on the bus arbitration scheduling. This should be investigated further in case of performance issues. The tested card contains an EEPROM on one of the 878A, but it is completely empty (i.e. contains only 0xff), so it is not possible to detect the card.
