' 47 This config option was moved to the defconfig 48 49 - CONFIG_... is not defined in Kconfig. Do nothing. 50 The entry for this CONFIG was not found in Kconfig. 51 There are two common cases: 52 - You forgot to create an entry for the CONFIG before running 53 this tool, or made a typo in a CONFIG passed to this tool. 54 - The entry was hidden due to unmet 'depends on'. 55 This is correct behavior. 56 57 - 'CONFIG_...' is the same as the define in Kconfig. Do nothing. 58 The define in the config header matched the one in Kconfig. 59 We do not need to touch it. 60 61 - Undefined. Do nothing. 62 This config option was not found in the config header. 63 Nothing to do. 64 65 - Compiler is missing. Do nothing. 66 The compiler specified for this architecture was not found 67 in your PATH environment. 68 (If -e option is passed, the tool exits immediately.) 69 70 - Failed to process. 71 An error occurred during processing this defconfig. Skipped. 72 (If -e option is passed, the tool exits immediately on error.) 73 74Finally, you will be asked, Clean up headers? [y/n]: 75 76If you say 'y' here, the unnecessary config defines are removed 77from the config headers (include/configs/*.h). 78It just uses the regex method, so you should not rely on it. 79Just in case, please do 'git diff' to see what happened. 80 81 82How does it work? 83----------------- 84 85This tool runs configuration and builds include/autoconf.mk for every 86defconfig. The config options defined in Kconfig appear in the .config 87file (unless they are hidden because of unmet dependency.) 88On the other hand, the config options defined by board headers are seen 89in include/autoconf.mk. The tool looks for the specified options in both 90of them to decide the appropriate action for the options. If the given 91config option is found in the .config, but its value does not match the 92one from the board header, the config option in the .config is replaced 93with the define in the board header. Then, the .config is synced by 94"make savedefconfig" and the defconfig is updated with it. 95 96For faster processing, this tool handles multi-threading. It creates 97separate build directories where the out-of-tree build is run. The 98temporary build directories are automatically created and deleted as 99needed. The number of threads are chosen based on the number of the CPU 100cores of your system although you can change it via -j (--jobs) option. 101 102 103Toolchains 104---------- 105 106Appropriate toolchain are necessary to generate include/autoconf.mk 107for all the architectures supported by U-Boot. Most of them are available 108at the kernel.org site, some are not provided by kernel.org. 109 110The default per-arch CROSS_COMPILE used by this tool is specified by 111the list below, CROSS_COMPILE. You may wish to update the list to 112use your own. Instead of modifying the list directly, you can give 113them via environments. 114 115 116Available options 117----------------- 118 119 -c, --color 120 Surround each portion of the log with escape sequences to display it 121 in color on the terminal. 122 123 -d, --defconfigs 124 Specify a file containing a list of defconfigs to move 125 126 -n, --dry-run 127 Perform a trial run that does not make any changes. It is useful to 128 see what is going to happen before one actually runs it. 129 130 -e, --exit-on-error 131 Exit immediately if Make exits with a non-zero status while processing 132 a defconfig file. 133 134 -H, --headers-only 135 Only cleanup the headers; skip the defconfig processing 136 137 -j, --jobs 138 Specify the number of threads to run simultaneously. If not specified, 139 the number of threads is the same as the number of CPU cores. 140 141 -v, --verbose 142 Show any build errors as boards are built 143 144To see the complete list of supported options, run 145 146 $ tools/moveconfig.py -h 147 148""" 149 150import fnmatch 151import multiprocessing 152import optparse 153import os 154import re 155import shutil 156import subprocess 157import sys 158import tempfile 159import time 160 161SHOW_GNU_MAKE = 'scripts/show-gnu-make' 162SLEEP_TIME=0.03 163 164# Here is the list of cross-tools I use. 165# Most of them are available at kernel.org 166# (https://www.kernel.org/pub/tools/crosstool/files/bin/), except the followings: 167# arc: https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases 168# blackfin: http://sourceforge.net/projects/adi-toolchain/files/ 169# nds32: http://osdk.andestech.com/packages/nds32le-linux-glibc-v1.tgz 170# nios2: https://sourcery.mentor.com/GNUToolchain/subscription42545 171# sh: http://sourcery.mentor.com/public/gnu_toolchain/sh-linux-gnu 172# 173# openrisc kernel.org toolchain is out of date, download latest one from 174# http://opencores.org/or1k/OpenRISC_GNU_tool_chain#Prebuilt_versions 175CROSS_COMPILE = { 176 'arc': 'arc-linux-', 177 'aarch64': 'aarch64-linux-', 178 'arm': 'arm-unknown-linux-gnueabi-', 179 'avr32': 'avr32-linux-', 180 'blackfin': 'bfin-elf-', 181 'm68k': 'm68k-linux-', 182 'microblaze': 'microblaze-linux-', 183 'mips': 'mips-linux-', 184 'nds32': 'nds32le-linux-', 185 'nios2': 'nios2-linux-gnu-', 186 'openrisc': 'or1k-elf-', 187 'powerpc': 'powerpc-linux-', 188 'sh': 'sh-linux-gnu-', 189 'sparc': 'sparc-linux-', 190 'x86': 'i386-linux-' 191} 192 193STATE_IDLE = 0 194STATE_DEFCONFIG = 1 195STATE_AUTOCONF = 2 196STATE_SAVEDEFCONFIG = 3 197 198ACTION_MOVE = 0 199ACTION_NO_ENTRY = 1 200ACTION_NO_CHANGE = 2 201 202COLOR_BLACK = '0;30' 203COLOR_RED = '0;31' 204COLOR_GREEN = '0;32' 205COLOR_BROWN = '0;33' 206COLOR_BLUE = '0;34' 207COLOR_PURPLE = '0;35' 208COLOR_CYAN = '0;36' 209COLOR_LIGHT_GRAY = '0;37' 210COLOR_DARK_GRAY = '1;30' 211COLOR_LIGHT_RED = '1;31' 212COLOR_LIGHT_GREEN = '1;32' 213COLOR_YELLOW = '1;33' 214COLOR_LIGHT_BLUE = '1;34' 215COLOR_LIGHT_PURPLE = '1;35' 216COLOR_LIGHT_CYAN = '1;36' 217COLOR_WHITE = '1;37' 218 219### helper functions ### 220def get_devnull(): 221 """Get the file object of '/dev/null' device.""" 222 try: 223 devnull = subprocess.DEVNULL # py3k 224 except AttributeError: 225 devnull = open(os.devnull, 'wb') 226 return devnull 227 228def check_top_directory(): 229 """Exit if we are not at the top of source directory.""" 230 for f in ('README', 'Licenses'): 231 if not os.path.exists(f): 232 sys.exit('Please run at the top of source directory.') 233 234def check_clean_directory(): 235 """Exit if the source tree is not clean.""" 236 for f in ('.config', 'include/config'): 237 if os.path.exists(f): 238 sys.exit("source tree is not clean, please run 'make mrproper'") 239 240def get_make_cmd(): 241 """Get the command name of GNU Make. 242 243 U-Boot needs GNU Make for building, but the command name is not 244 necessarily "make".
