Subject: [PATCH v2] ARM: highbank: fix debug uart virtual address for LPAE
Date: Sat, 17 Aug 2013 19:12:28 -0500 [thread overview]
Message-ID: <1376784748-31914-1-git-send-email-robherring2@gmail.com> (raw)
From: Rob Herring <rob.herring@calxeda.com>
Section entries are 2MB on LPAE, so the DEBUG_LL virtual address must
have the same offset in the 2MB section as the physical address. This
fixes async external aborts when DEBUG_LL is enabled on Midway.
