o Allow for up to 3 resource I/O ranges to be given for the floppy controller, rather than just two that are allowed for now. o Make sure that we can work with either a base address of 0x3f0 or 0x3f2. o Create new inline functions to access the YE DATA's unique BDCR register. o Update pccard attachment to add the fd device. o Do some minor style(9) polishing. # I'm guessing that the fdc pccard attachment broke some time ago, since # there are a number of issues with it still.
