From 4bacd796ccd6976b03dd490708a1abc291d5521e Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Sat, 2 Oct 2010 22:02:07 +0900 Subject: sh: Support early IRQ vector map reservation for delayed controllers. Some controllers will need to be initialized lazily due to pinmux constraints, while others may simply have no need to be brought online if there are no backing devices for them attached. In this case it's still necessary to be able to reserve their hardware vector map before dynamic IRQs get a hold of them.
