why is entire 8xx architecture defined as "broken"?

[Robert P. J. Day]

  after i looked at the Kconfig setup for 2.6.11-5, i'm a bit puzzled
-- why is the entire 8xx architecture defined as "BROKEN"?  follow the
logic along:

arch/ppc/Kconfig:

        config 8xx
                depends on BROKEN
                bool "8xx"

  and what means "BROKEN"?

init/Kconfig:

        config BROKEN
                bool
                depends on !CLEAN_COMPILE
                default y

  ok, and "CLEAN_COMPILE"?  defined just above that:

        config CLEAN_COMPILE
                bool "Select only drivers expected to compile cleanly" if
                        EXPERIMENTAL
                default y

  ok, and "EXPERIMENTAL"?

        config EXPERIMENTAL
                bool "Prompt for development and/or incomplete code/drivers"

and *that* refers to the top-level menu entry regarding whether you
want to take a chance on "development and/or incomplete code/drivers",
not entire architectures.

  the above seems just a tad misleading, no?
