From ede2033c405bfbd6b74b113cf69c6f54cef35902 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Fri, 6 Sep 2013 16:49:18 -0500 Subject: openrisc: clean-up prom.h Clean-up some copy/paste declarations that are not necessary. All the functions either don't exist or are already declared in other headers. This is needed in preparation of of_irq.h clean-up.
