Yann E. MORIN 1925a276af scripts/config: fix double-quotes un-escaping
When reporting a string value, only the first double-quote was
un-escaped. We need to un-escape all escaped double-quotes.

Yann E. MORIN d5bfb6b381 scripts/config: add option to undef a symbol
It is currently possible to enable, disable or modularise
a symbol. Also, an undefined symbol is reported as such.

Add a new command to undefine a symbol, by removing the
corresponding line from the .config file.

Yann E. MORIN f5ef2f7bf2 scripts/config: allow alternate prefix to config option symbol
While the Linux kernel uses 'CONFIG_' as a prefix to the config options
symbols, many projects that use kconfig may use different prefixes, or
even none at all.

If the CONFIG_ environment variable is set, use it as the prefix (empty
is a valid prefix). Otherwise, use the default prefix 'CONFIG_'.

This matches the support for alternate prefixes in scripts/kconfig/lkc.h,
which uses the same logic (albeit with a C define instead of an environment
variable).

Yann E. MORIN 4edc7e32af 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.

Yann E. MORIN d6686da814 scripts/config: properly report and set string options
Currently, scripts/config removes the leading double-quote from
string options, but leaves the trailing double-quote.

Also, double-quotes in a string are escaped, but scripts/config
does not unescape those when printing

Finally, scripts/config does not escape double-quotes when setting
string options.

Eg. the current behavior:
    $ grep -E '^CONFIG_FOO=' .config
    CONFIG_FOO="Bar \"Buz\" Meh"
    $ ./scripts/config -s FOO
    Bar \"Buz\" Meh"
    $ ./scripts/config --set-str FOO 'Alpha "Bravo" Charlie'
    $ grep -E '^CONFIG_FOO=' .config
    CONFIG_FOO="Alpha "Bravo" Charlie"

Fix those three, giving this new behavior:
    $ grep -E '^CONFIG_FOO=' .config
    CONFIG_FOO="Bar \"Buz\" Meh"
    $ ./scripts/config -s FOO
    Bar "Buz" Meh
    $ ./scripts/config --set-str FOO 'Alpha "Bravo" Charlie'
    $ grep -E '^CONFIG_FOO=' .config
    CONFIG_FOO="Alpha \"Bravo\" Charlie"

Andi Kleen 8e54701ea8 kconfig: add script to manipulate .config files on the command line
I often change single options in .config files. Instead of using
an editor or one of the frontends it's convenient to do this from
the command line. It's also useful to do from automated build scripts
when building different variants from a base config file.

I extracted most of the CONFIG manipulation code from one of my
build scripts into a new shell script scripts/config

The script is not integrated with the normal Kconfig machinery
and doesn't do any checking against Kconfig files, but just manipulates
that text format. This is always done at make time anyways.

I believe this script would be a useful standard addition for scripts/*

Sample usage:

./scripts/config --disable smp
Disable SMP in .config file

./scripts/config --file otherdir/.config --module e1000e
Enable E1000E as module in otherdir/.config

./scripts/config --state smp
y
Check state of config option CONFIG_SMP

After merging into git please make scripts/config executable
