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.
