Subject: [UPDATE PATCH] Fix bcmring IO mem mapping.

From: [email-masked] (Jiandong Zheng)
Date: Mon, 14 May 2012 17:23:16 -0700

BCMRING IO mem static mapping table has overlapping entries which causes bcmring booting issue since v3.2 when kernel started checking this problem.

It should be fixed anyway so that they are consolidated to make sure the table is valid.
Comments are also updated accordingly.
