From 4a995edec1ac163d9326d143ffe2b47e7543407f Mon Sep 17 00:00:00 2001 From: Marian Balakowicz Date: Thu, 31 Jan 2008 13:20:06 +0100 Subject: [new uImage] Rename architecture specific bootm code files Implementation of the do_bootm_linux() and other bootm helper routines is architecture specific code. As such it resides in lib_ directories in files named _linux.c This patch renames those files to a more clear and accurate lib_/bootm.c form. List of the renamed files: lib_arm/armlinux.c -> lib_arm/bootm.c lib_avr32/avr32_linux.c -> lib_avr32/bootm.c lib_blackfin/bf533_linux.c -> lib_blackfin/bootm.c lib_i386/i386_linux.c -> lib_i386/bootm.c lib_m68k/m68k_linux.c -> lib_m68k/bootm.c lib_microblaze/microblaze_linux.c -> lib_microblaze/bootm.c lib_mips/mips_linux.c -> lib_mips/bootm.c lib_nios/nios_linux.c -> lib_nios/bootm.c lib_nios2/nios_linux.c -> lib_nios2/bootm.c lib_ppc/ppc_linux.c -> lib_ppc/bootm.c lib_sh/sh_linux.c -> lib_sh/bootm.c Signed-off-by: Marian Balakowicz --- lib_i386/Makefile | 2 +- lib_i386/bootm.c | 142 ++++++++++++++++++++++++++++++++++++++++++++++++++ lib_i386/i386_linux.c | 142 -------------------------------------------------- 3 files changed, 143 insertions(+), 143 deletions(-) create mode 100644 lib_i386/bootm.c delete mode 100644 lib_i386/i386_linux.c (limited to 'lib_i386') diff --git a/lib_i386/Makefile b/lib_i386/Makefile index e344da515..ef0ba5467 100644 --- a/lib_i386/Makefile +++ b/lib_i386/Makefile @@ -27,7 +27,7 @@ LIB = $(obj)lib$(ARCH).a SOBJS = bios.o bios_pci.o realmode_switch.o -COBJS = board.o bios_setup.o i386_linux.o zimage.o realmode.o \ +COBJS = board.o bios_setup.o bootm.o zimage.o realmode.o \ pci_type1.o pci.o video_bios.o video.o SRCS := $(SOBJS:.o=.S) $(COBJS:.o=.c) diff --git a/lib_i386/bootm.c b/lib_i386/bootm.c new file mode 100644 index 000000000..27a2b0d9a --- /dev/null +++ b/lib_i386/bootm.c @@ -0,0 +1,142 @@ +/* + * (C) Copyright 2002 + * Sysgo Real-Time Solutions, GmbH + * Marius Groeger + * + * Copyright (C) 2001 Erik Mouw (J.A.K.Mouw@its.tudelft.nl) + * + * 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.
