Subject: [PATCH v2 36/44] Add metag to various Kconfig dependency lists
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
