The sed script, tools/scripts/define2mk.sed, converts config defines from C headers into include/autoconf.mk for the use in Makefiles. I found the tool adds quotes around negative integer values. For example, at the point of the v2016.07-rc1 tag, include/configs/microblaze-generic.h defines #define CONFIG_BOOTDELAY -1 /* -1 disables auto-boot */ Because it is an integer option, it should be converted to: CONFIG_BOOTDELAY=-1 But, the script actually converts it to: CONFIG_BOOTDELAY="-1" This is a fatal problem for the tools/moveconfig.py because it parses include/autoconf.mk for the config defines from the board headers. CONFIG_BOOTDELAY="-1" is considered as a string type option and it is dropped due to the type mismatch from the entry in Kconfig. This commit fixes the script so that the tools/moveconfig.py can correctly convert integer options with a negative value. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
