Re: software reset

[Ronald G Minnich]

I'm going to do something much like what we do for other mainboard
functions in linux (see irq setup). 

I'll have an struct like so: 

struct resethardware {
        unsigned short vendor, device;
        unsigned char registernumber;
        unsigned char bit;
        unsigned char val;
};

This will be populated with an array of things, viz:
struct resethardware resets[] = {
        /* note: I know these are the wrong bits */
        {VENDOR_INTEL, PIIX4E, 0x3c, 0x5, 1},
        {VENDOR_SIS, SIS630, 0x47, 0x5, 0}
};

Then you call hardware reset. 

Hardware reset does this:

1) find the first pcidev in the resets array that matches the actual
   hardware
2) using the pcidv, set bit 'bit' to val 'val' in register
   'registernumber'

Comments?
