Kconfig with multiple sources of integer value

I have a situation (and possibly some more) where having the ability
for multiple options to affect an integer value, in this case ensuring
a minimum value.

currently we have the following:

config S3C24XX_GPIO_EXTRA
int
default 128 if S3C24XX_GPIO_EXTRA128
default 64 if S3C24XX_GPIO_EXTRA64
default 0

and various machines select S3C24XX_GPIO_EXTRA64 or S3C24XX_GPIO_EXTR128
such as:

config MACH_OSIRIS
...
select S3C24XX_GPIO_EXTRA128


It would be nice if I could say

config S3C24XX_GPIO_EXTRA

and then

config MACH_OSIRIS
...
set_min S3C24XX_GPIO_EXTRA 128

or something similar.
