you miss my point here
as if you can use the get_hw_rev multiple time then please do something like
thie

static int hw_rev = -1;	/* hardware revision */

int get_hw_rev(void)
{
	if (hw_rev >= 0)
		return hw_rev;

	hw_rev = at91_get_gpio_value(AT91_PIN_PB19);

	hw_rev |= at91_get_gpio_value(AT91_PIN_PB20) << 1;
	hw_rev |= at91_get_gpio_value(AT91_PIN_PB21) << 2;
	hw_rev |= at91_get_gpio_value(AT91_PIN_PB22) << 3;

	if (hw_rev == 15)
		hw_rev = 0;

	return hw_rev;
}

CONFIG_AT91_CAN will be better as the code is at91 specific
