    Subject[PATCH v2 36/44] Add metag to various Kconfig dependency lists
    Date
    Add [!]METAG to various Kconfig dependencies in generic code, as
    described below:

    - Kconfig.debug: don't allow stack utilization instrumentation on
    metag, and allow building with frame pointers.

    - char: don't build rtc or genrtc on METAG
    The metag architecture doesn't have a PC RTC or implement the
    RTC interface that genrtc expects, so add METAG to the list of
    architectures not to build RTC or GEN_RTC on.

    - i8042: don't build on METAG
    The metag architecture port doesn't support the i8042 keyboard
    controller, so add METAG to the list of architectures not to
    build it's driver on.

    - parport: don't build on METAG
    The metag architecture port doesn't support PC parallel ports,
    so add METAG to the list of architectures not to build it's
    driver on.

    - vga console: don't build on METAG
    The metag architecture doesn't support VGA so add METAG to the
    list of architectures not to build support on.

    TODO: invert the dependency logic of most of these with the help of a
    new LEGACY_PC_IO Kconfig symbol
