at risk of boring, i'll mention a couple more scripts i have for locating oddities or inconsistencies in the Kbuild structure, which people are welcome to play with.
the first is called "find_badref_selects.sh", which specifically locates "select" directives in Kconfig files that are selecting non-existing Kbuild options, which makes them pointless.
example (focusing attention on arch/arm directory):
$ find_badref_selects.sh arch/arm
CPU_ARM926EJS1
arch/arm/mach-imx/mx2/Kconfig:20: select CPU_ARM926EJS1
SPL_DISABLE_OF_CONTROL
arch/arm/mach-exynos/Kconfig:119: select SPL_DISABLE_OF_CONTROL arch/arm/mach-exynos/Kconfig:153: select SPL_DISABLE_OF_CONTROL $
and a second script called "find_badref_make_configs.sh" specifically finds Kconfig references in Makefiles that point to non-existent Kconfig options. for example:
$ find_badref_make_configs.sh drivers/gpio
ADI_GPIO2
./drivers/gpio/Makefile:obj-$(CONFIG_ADI_GPIO2) += adi_gpio2.o
DB8500_GPIO
./drivers/gpio/Makefile:obj-$(CONFIG_DB8500_GPIO) += db8500_gpio.o
DM644X_GPIO
./drivers/gpio/Makefile:obj-$(CONFIG_DM644X_GPIO) += da8xx_gpio.o $
if anyone's interested, i can post those scripts on a couple more wiki pages this weekend, with an example or two. and on that note, i will shut up about this now.
