Subject: [PATCH 2/4] ARM: tegra: uncompress.h: Store UART address in a variable
Date: Tue, 3 Jan 2012 15:25:18 -0700 [thread overview]
Message-ID: <1325629520-23018-3-git-send-email-swarren@nvidia.com> (raw)
In-Reply-To: <1325629520-23018-1-git-send-email-swarren@nvidia.com>
From: Doug Anderson <dianders@chromium.org>
This will allow a future change to auto-detect which UART to use.
