Author: marcel Date: Sat Jan 29 20:25:20 2011 New Revision: 218073 URL: http://svn.freebsd.org/changeset/base/218073 Log: Introduce macro FDT_MAP_IRQ to map from an interrupt controller and interrupt pin pair to a global IRQ number. When multiple PICs exist on a board, the interrupt pin alone is not unique.
