i can't imagine where to find the addresses, i searched in edosk7760 and 
smc91c96 manuals; others implementations that use this NIC ...
someone knows? it's really necessary?


currently i have:

#define SMC_IOADDR 0xA2000000

static struct resource smc91x_res[] = {
         [0] = {
		.start  = SMC_IOADDR,
		.end    = SMC_IOADDR + 0x1f,
		.flags  = IORESOURCE_MEM,
         },
         [1] = {
		.start  = ETHERNET_IRQ,
		.end    = ETHERNET_IRQ,
		.flags  = IORESOURCE_IRQ,
         },

/*
		[2] = {
		.name = "smc91x-attrib",
		.start  = SMC_IOADDR + 0x02000000,
		.end    = SMC_IOADDR + 0x03ffffff,
		.flags = IORESOURCE_MEM,
		},
*/

};
