From 1c9cf6f9861f8d27303ee2531b3b7686269c71ce Mon Sep 17 00:00:00 2001 From: Deepak Saxena Date: Fri, 26 Aug 2005 18:34:11 -0700 Subject: [PATCH] [PATCH] arm: fix IXP4xx flash resource range We are currently reserving one byte more than actually needed by the flash device and overlapping into the next I/O expansion bus window. This a) causes us to allocate an extra page of VM due to ARM ioremap() alignment code and b) could cause problems if another driver tries to request the next expansion bus window.
