Subject: Kconfig question - multiple entries touching one integer

I'm trying to produce a Kconfig to deal with allocating
extra resources depending on what is selected. I'd like
to have an integer which specifies the 

ie:

config ARCH_EXTRA_RESOURCES
	int
	default 0
	help
	  Extra resources depending on the board selected

...

config BOARD_A
	set ARCH_EXTRA_RESOURCES 32

config BOARD_B
	set ARCH_EXTRA_RESOURCES 64

in this example, if board A is selected, then ARCH_EXTRA_RESOURCES
would be 32, if BOARD_B is selected then it would be 64.

doing

	config ARCH_EXTRA_RESOURCES
	int
	default 0
	default 32 if BOARD_A
	default 64 if BOARD_B

doesn't work, and involves changing this part of the Kconfig
every time a new board is added.

Is there any current way of doing this, would there be any
objections to having some form of 'set' clause in a config
statememt?
