From 0d256bdc8f540a52fe1f0475aeeed3bc9f6e2de4 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 13 Apr 2012 11:39:09 +0000 Subject: hw/arm_gic: Use NVIC instead of LEGACY_INCLUDED_GIC define Now all the A profile cores have been switched to use the standalone sysbus GIC, the only remaining code which #includes arm_gic.c is the v7M NVIC. The coupling is much closer here so it's not so easily disentangled. For now, add a comment about how arm_gic.c is compiled, and assume that the NVIC always includes arm_gic.c and the non-NVIC GIC is always compiled standalone.
