Either you put that comment at the beginning of the file, or at the end,
not in the middle.

The reason is that Kconfig, when it detects a dependnecy chain between
two adjacent symbols, will render the second symbol indented below the
first, like so:

    config FOO
        bool "foo"

    config BAR
        boll "bar'
        depends on FOO

will be render in the menuconfig as:

    [*] foo
    [ ]   bar

To show that 'bar' is a sub-option of 'foo'.

If you put the comment in between FOO nad BAR, then you break the
"dependency chain" and the symbols will be rendred as:

    [*] foo
    [ ] bar

which is less than ideal.

[I haven't looked at the rest of the file, as I know about nothing about
sdl2]

Yann E. MORIN.
