From 28fd4b7228620f915dd837d401abaab8c353e89c Mon Sep 17 00:00:00 2001
From: Jens Arnold <amiconn@rockbox.org>
Date: Tue, 19 Dec 2006 09:27:41 +0000
Subject: Archos: Moved the ata_address_detect() code into ata_device_init(),
 removing the associated #ifdef and some public #defines. Saves a tiny bit of
 code as well.
