scripts/config: add option to not upper-case symbols
Currently, scripts/config mangles the config option symbols to always be upper-case. While the Linux kernel almost exclusively uses upper-case symbols, there are still a few symbols with lower-case which this script can not handle: $ grep -r -E '^[[:space:]]*config[[:space:]]+[^[:space:]]*[[:lower:]][^[:space:]=.]*$' . |wc -l 173 (that's roughly 1.3% of the symbols in 3.5-rc1) Eg.: ./arch/arm/Kconfig:config VFPv3 ./arch/powerpc/platforms/Kconfig.cputype:config 40x ./arch/x86/Kconfig:config SCx200HR_TIMER ./drivers/video/console/Kconfig:config FONT_8x8 ./drivers/video/Kconfig:config NTSC_640x480 Also, other projects that use kconfig may allow for lower- or mixed-case symbols, and may find easier to reuse this script than implement each their own (potentially flawed) logic. For such a use-case, see: http://marc.info/?l=linux-kbuild&m=133409932115848&w=2 This patch adds a new option to keep the given case, and keep the current default to upper-case the symbols.
