Power ISA v3.0 (and later) implementations in the Linux Compliancy Subset and lower are not required to implement broadcast TLBIE, and in fact Microwatt doesn't. To avoid the need to specify "disable_tlbie" on the kernel command line on SMP Microwatt systems, this defines a config option that asserts that the platform implements broadcast TLBIE. This option is selected by the pseries and powernv platforms, but not by microwatt. Note that this option is only relevant when the radix MMU is being used, so platforms without a radix MMU don't need it.
