From: Marian Balakowicz Date: Thu, 31 Jan 2008 12:20:06 +0000 (+0100) Subject: [new uImage] Rename architecture specific bootm code files X-Git-Tag: v1.3.3-rc1~141^2^2~75 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=4a995edec1ac163d9326d143ffe2b47e7543407f;p=oweals%2Fu-boot.git [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 --- diff --git a/lib_arm/Makefile b/lib_arm/Makefile index 037c475f8b..aa9bee75cc 100644 --- a/lib_arm/Makefile +++ b/lib_arm/Makefile @@ -27,7 +27,7 @@ LIB = $(obj)lib$(ARCH).a SOBJS = _ashldi3.o _ashrdi3.o _divsi3.o _modsi3.o _udivsi3.o _umodsi3.o -COBJS = armlinux.o board.o \ +COBJS = bootm.o board.o \ cache.o div0.o SRCS := $(SOBJS:.o=.S) $(COBJS:.o=.c) diff --git a/lib_arm/armlinux.c b/lib_arm/armlinux.c deleted file mode 100644 index 4f9aae613e..0000000000 --- a/lib_arm/armlinux.c +++ /dev/null @@ -1,384 +0,0 @@ -/* - * (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.
