Beware - things have changed around here - relevant hunks from my

This enables support for systems with more than one CPU. If you have
a system with only one CPU, like most personal computers, say N. If

Enable support for local timers on SMP platforms, rather then the
legacy IPI broadcast method. Local timers allows the system
Basically, everyone who was supporting SMP also supported local timers,
TWD and SCU, so having the big long lists of dependencies was becoming
silly.
If anyone (ever) creates a SMP implementation not using ARMs TWD/GIC/SCU,
then we can see about changing the way we handle the support for these.
