Subject: [PATCH v4 04/13] ARM: LPAE: use phys_addr_t for initrd location
Date: Thu, 31 Jan 2013 16:58:23 -0500 [thread overview]
Message-ID: <1359669512-31276-5-git-send-email-cyril@ti.com> (raw)
In-Reply-To: <1359669512-31276-1-git-send-email-cyril@ti.com>
From: Vitaly Andrianov <vitalya@ti.com>
This patch fixes the initrd setup code to use phys_addr_t instead of assuming
32-bit addressing. Without this we cannot boot on systems where initrd is
located above the 4G physical address limit.
