From 76164e1a3659d623cbd8b704559bf6241521011f Mon Sep 17 00:00:00 2001 From: Jonas Gorski Date: Mon, 13 Jan 2014 12:13:26 +0000 Subject: [PATCH] brcm63xx: add support for chip variants Some SoCs have variants which are mostly the same, but use a different chip id (or not). Add code for detecting them and handling them as their standard counterparts. This adds support for e.g. BCM6369.
