#     powerpc/configs: Don't enable PPC_EARLY_DEBUG in defconfigs
#     
#     This reverts the remains of commit b9ef7d6b11c1 ("powerpc: Update
#     default configurations").
#     
#     That commit was proceeded by a commit which added a config option to
#     control use of BOOTX for early debug, ie. PPC_EARLY_DEBUG_BOOTX, and
#     then the update of the defconfigs was intended to not change behaviour
#     by then enabling the new config option.
#     
#     However enabling PPC_EARLY_DEBUG had other consequences, notably
#     causing us to register the udbg console at the end of udbg_early_init().
#     
#     This means on a system which doesn't have anything that BOOTX can
#     use (most systems), we register the udbg console very early but the
#     bootx code just throws everything away, meaning early boot messages
#     are never printed to the console.
#     
#     What we want to happen is for the udbg console to only be registered
#     later (from setup_arch()) once we've setup udbg_putc, and then all
#     early boot messages will be replayed.
#
