mcb: Added bar descriptor support for non PCI bus MCB carrier Added support for the bar descriptor. This type is used for FPGAs connect to the LPC or to a non PCI bus. The Bar descriptor could have a maximum of 6 BARs. Each of the devices within the FPGA could be mapped to a different BAR. The BAR descriptor is comparable to the PCI header.

mcb: Return actual parsed size when reading chameleon table The function chameleon_parse_cells() returns the number of cells parsed which has an undetermined size. This return value is only used for error checking but the number of cells is never used. Change return value to be number of bytes parsed to allow for memory management improvements.

mcb: Added bar descriptor support for non PCI bus MCB carrier Added support for the bar descriptor. This type is used for FPGAs connect to the LPC or to a non PCI bus. The Bar descriptor could have a maximum of 6 BARs. Each of the devices within the FPGA could be mapped to a different BAR. The BAR descriptor is comparable to the PCI header.
