From 18bacc2027f8531d8dec15ba8da3242dfb4e63f3 Mon Sep 17 00:00:00 2001 From: Poonam Aggrwal Date: Fri, 31 Jul 2009 12:07:45 +0530 Subject: 8xxx: Refactored common cpu specific code for 85xx/86xx into one file. Removed same code pieces from cpu/mpc85xx/cpu.c and cpu/mpc86xx/cpu.c and moved to cpu/mpc8xxx/cpu.c(new file) Signed-off-by: Poonam Aggrwal Signed-off-by: Kumar Gala --- cpu/mpc8xxx/Makefile | 25 ++++++++++++ cpu/mpc8xxx/cpu.c | 106 +++++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 131 insertions(+) create mode 100644 cpu/mpc8xxx/Makefile create mode 100644 cpu/mpc8xxx/cpu.c (limited to 'cpu/mpc8xxx') diff --git a/cpu/mpc8xxx/Makefile b/cpu/mpc8xxx/Makefile new file mode 100644 index 0000000..430a75f --- /dev/null +++ b/cpu/mpc8xxx/Makefile @@ -0,0 +1,25 @@ +# +# Copyright 2009 Freescale Semiconductor, Inc. +# +# This program is free software; you can redistribute it and/or +# modify it under the terms of the GNU General Public License +# Version 2 as published by the Free Software Foundation. +# + +include $(TOPDIR)/config.mk + +LIB = $(obj)lib8xxx.a + +COBJS-y += cpu.o + +SRCS := $(START:.o=.S) $(SOBJS-y:.o=.S) $(COBJS-y:.o=.c) +OBJS := $(addprefix $(obj),$(SOBJS-y) $(COBJS-y)) + +all: $(obj).depend $(LIB) + +$(LIB): $(OBJS) + $(AR) $(ARFLAGS) $@ $(OBJS) + +include $(SRCTREE)/rules.mk + +sinclude $(obj).depend diff --git a/cpu/mpc8xxx/cpu.c b/cpu/mpc8xxx/cpu.c new file mode 100644 index 0000000..e34ef33 --- /dev/null +++ b/cpu/mpc8xxx/cpu.c @@ -0,0 +1,106 @@ +/* + * Copyright 2009 Freescale Semiconductor, Inc. + * + * This file is derived from cpu/mpc85xx/cpu.c and cpu/mpc86xx/cpu.c. + * Basically this file contains cpu specific common code for 85xx/86xx + * processors. + * See file CREDITS for list of people who contributed to this + * project. + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License as + * published by the Free Software Foundation; either version 2 of + * the License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
