From efa35cf12d914d4caba942acd5a6c45f217de302 Mon Sep 17 00:00:00 2001 From: Grzegorz Bernacki Date: Fri, 15 Jun 2007 11:19:28 +0200 Subject: ppc4xx: Clean up 440 exceptions handling - Introduced dedicated switches for building 440 and 405 images required for 440-specific machine instructions like 'rfmci' etc. - Exception vectors moved to the proper location (_start moved away from the critical exception handler space, which it occupied) - CriticalInput now serviced (with default handler) - MachineCheck properly serviced (added a dedicated handler and return subroutine) - Overall cleanup of exceptions declared with STD_EXCEPTION macro (unused, unhandled and those not relevant for 4xx were eliminated) - Eliminated Linux leftovers, removed dead code Signed-off-by: Grzegorz Bernacki Signed-off-by: Rafal Jaworowski Signed-off-by: Stefan Roese --- cpu/ppc4xx/config.mk | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) (limited to 'cpu/ppc4xx/config.mk') diff --git a/cpu/ppc4xx/config.mk b/cpu/ppc4xx/config.mk index 119e061b89..e7fc3f636e 100644 --- a/cpu/ppc4xx/config.mk +++ b/cpu/ppc4xx/config.mk @@ -22,5 +22,13 @@ # PLATFORM_RELFLAGS += -fPIC -ffixed-r14 -meabi -fno-strict-aliasing +PLATFORM_CPPFLAGS += -DCONFIG_4xx -ffixed-r2 -ffixed-r29 -mstring -msoft-float -PLATFORM_CPPFLAGS += -DCONFIG_4xx -ffixed-r2 -ffixed-r29 -mstring -Wa,-m405 -mcpu=405 -msoft-float +cfg=$(shell grep configs $(TOPDIR)/include/config.h | sed 's/.*<\(configs.*\)>/\1/') +is440=$(shell grep CONFIG_440 $(TOPDIR)/include/$(cfg)) + +ifneq (,$(findstring CONFIG_440,$(is440))) +PLATFORM_CPPFLAGS += -Wa,-m440 -mcpu=440 +else +PLATFORM_CPPFLAGS += -Wa,-m405 -mcpu=405 +endif -- cgit
