+From cf7086d4c2f7caeccd019c0a57bf1566c72c13ee Mon Sep 17 00:00:00 2001
+From: John Crispin <blogic@openwrt.org>
+Date: Wed, 10 Aug 2011 14:57:04 +0200
+Subject: [PATCH 05/70] MIPS: lantiq: reorganize xway code
+
+Inside the folder arch/mips/lantiq/xway, there were alot of small files with
+lots of duplicated code. This patch adds a wrapper function for inserting and
+requesting resources and unifies the small files into one bigger file.
+
+This patch makes the xway code consistent with the falcon support added later
+in this series.
+
+Signed-off-by: John Crispin <blogic@openwrt.org>
