Subject: [PATCH v2 09/22] ARM: LPAE: use phys_addr_t for initrd location and size
Date: Fri, 10 Aug 2012 21:24:52 -0400 [thread overview]
Message-ID: <1344648306-15619-10-git-send-email-cyril@ti.com> (raw)
In-Reply-To: <1344648306-15619-1-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.
