From 4eeddefb220bd89ef862ac75e0239795637cca77 Mon Sep 17 00:00:00 2001 From: Pavel Pisa Date: Thu, 25 Jul 2013 10:34:50 +0200 Subject: [PATCH] bsp/csb336: mc9328mxl correct AITC access in bsp_interrupt_dispatch. The original version is missing void and result is that (*x >> 16) is optimized to ldh rX,[rY]. But it is not allowed/supported to access bus/address range used by AITC by other than 32 bit wide accesses and 16-bit access results in the data abort exception. The corrected version works on real hardware and is even more readable.
