To override specific configuration items, such as the number of external interrupts,
you can create your own Configuration(s) and compose them with Config's ++ operator
class WithNExtInterrupts extends Config (nExt: Int) {
(pname, site, here) => pname match {
case (NExtInterrupts => nExt)
class WithNExtInterrupts(nExt: Int) extends Config {
(site, here, up) => {
case NExtInterrupts => nExt
}
}
class MyConfig extends Config (new WithNExtInterrupts(16) ++ new DefaultSmallConfig)
