From 97ceed1fc29b601e64af98fd785e25fec4383b12 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 24 Mar 2011 16:12:40 +0100 Subject: ARM: 6829/1: amba: make hardcoded periphid override hardware This makes a hardcoded periphid from the platform override any magic number found in the hardware. This shall henceforth be used when the information found in the hardware is either missing, i.e. not encoding the CID with the magic cookie 0xb105f00d, or incorrect such that the revision number should have been bumped in hardware, but the silicon designer has failed to do so.
