Subject[RFC][PATCH] kconfig: implement select with values
This is a fairly brute force approach to allowing a Kconfig "select"
to specify an excplicit value for the selected config sybmol.

The syntax of select is changed to:

"select" <symbol> [<expr>] ["if" expr]

The approach taken is to add a list of <value, dependency expression>
pairs to the symbol and check them whenever the reverse depends (from
a current-style select) are checked.

This is a work in progress, though it is possible to set values. I have
not done a great deal of testing.

I would like comments on the approach (and the actual code as the kconfig
code is pretty dense :-)).

This is built on top of the kbuild tree that is in linux-next
(git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild-2.6.git#for-next)
merged with Linus' tree of a few days ago (commit
2f7989efd4398d92b8adffce2e07dd043a0895fe "Merge
master.kernel.org:/home/rmk/linux-2.6-arm").

-- reverse dependencies: "select" <symbol> ["if" <expr>]
+- reverse dependencies: "select" <symbol> [<expr>] ["if" <expr>]
While normal dependencies reduce the upper limit of a symbol (see
below), reverse dependencies can be used to force a lower limit of
another symbol. The value of the current menu symbol is used as the
minimal value <symbol> can be set to. If <symbol> is selected multiple
times, the limit is set to the largest selection.
- Reverse dependencies can only be used with boolean or tristate
- symbols.
+ Reverse dependencies without the optional <expr> can only be used with
+ boolean or tristate symbols. If the optional <expr> is supplied,
+ the <symbol> will be set to that value if possible.
Note:
select should be used with care. select will force
a symbol to a value without visiting the dependencies.
