Using standard diff to compare .config files often includes extraneous and distracting information. This utility produces sorted output with only the changes in configuration values between the two files. Added and removed items are shown with a leading plus or minus, respectively. Changed items show the old and new values on a single line. If -m is specified, then output will be in "merge" style, which has the changed and new values in kernel config option format. If no config files are specified, .config and .config.old are used. Example usage: $ diffconfig .config config-with-some-changes -EXT2_FS_XATTR n CRAMFS n -> y EXT2_FS y -> n LOG_BUF_SHIFT 14 -> 16 PRINTK_TIME n -> y """) sys.exit(0) # returns a dictionary of name/value pairs for config items in the file def readconfig(config_file): d = {} for line in config_file: line = line[:-1] if line[:7] == "CONFIG_": name, val = line[7:].split("=", 1) d[name] = val if line[-11:] == " is not set": d[line[9:-11]] = "n" return d def print_config(op, config, value, new_value): global merge_style if merge_style: if new_value: if new_value=="n": print("# CONFIG_%s is not set" % config) else: print("CONFIG_%s=%s" % (config, new_value)) else: if op=="-": print("-%s %s" % (config, value)) elif op=="+": print("+%s %s" % (config, new_value)) else: print(" %s %s -> %s" % (config, value, new_value)) def show_diff(): global merge_style # parse command line args if ("-h" in sys.argv or "--help" in sys.argv): usage() merge_style = 0 if "-m" in sys.argv: merge_style = 1 sys.argv.remove("-m") argc = len(sys.argv) if not (argc==1 or argc == 3): print("Error: incorrect number of arguments or unrecognized option") usage() if argc == 1: # if no filenames given, assume .config and .config.old build_dir="" if "KBUILD_OUTPUT" in os.environ: build_dir = os.environ["KBUILD_OUTPUT"]+"/" configa_filename = build_dir + ".config.old" configb_filename = build_dir + ".config" else: configa_filename = sys.argv[1] configb_filename = sys.argv[2] try: a = readconfig(open(configa_filename)) b = readconfig(open(configb_filename)) except (IOError): e = sys.exc_info()[1] print("I/O error[%s]: %s\n" % (e.args[0],e.args[1])) usage() # print items in a but not b (accumulate, sort and print) old = [] for config in a: if config not in b: old.append(config) old.sort() for config in old: print_config("-", config, a[config], None) del a[config] # print items that changed (accumulate, sort, and print) changed = [] for config in a: if a[config] != b[config]: changed.append(config) else: del b[config] changed.sort() for config in changed: print_config("->", config, a[config], b[config]) del b[config] # now print items in b but not in a # (items from b that were in a were removed above) new = sorted(b.keys()) for config in new: print_config("+", config, None, b[config]) def main(): try: show_diff() except BrokenPipeError: # Python flushes standard streams on exit; redirect remaining output # to devnull to avoid another BrokenPipeError at shutdown devnull = os.open(os.devnull, os.O_WRONLY) os.dup2(devnull, sys.stdout.fileno()) sys.exit(1) # Python exits with error code 1 on EPIPE if __name__ == '__main__': main() e='linux-4.18.y'>linux-4.18.y Hosts the 0x221E linux distro kernel.Ubuntu

2022-11-15arm64: dts: broadcom: trim addresses to 8 digitsKrzysztof Kozlowski
Hex numbers in addresses and sizes should be rather eight digits, not nine. Drop leading zeros. No functional change (same DTB).

2022-04-07arm64: dts: broadcom: align SPI NOR node name with dtschemaKrzysztof Kozlowski
The node names should be generic and SPI NOR dtschema expects "flash". Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>

Broadcom ns2 platform has spi-cpol and spi-cpho properties set incorrectly. As per spi-slave-peripheral-prop.yaml, these properties are of flag or boolean type and not integer type. Fix the values.
