Subject: [PATCH/RFC] ARM: CONFIG_MTD_XIP vs. __aeabi_idiv
Message-ID: <20100909131403.GA28399@sig21.net>
To: linux-arm-kernel@lists.infradead.org
List-Id: linux-arm-kernel.lists.infradead.org

For testing purposes I needed to build a kernel which
executes in-place in NOR flash.  It crashes when probing
physmap flash because the MTD code which runs from RAM with
CONFIG_MTD_XIP calls __aeabi_idiv.
