Uwe Hermann a69772157e Document a rough estimate of how much space in the ELF file each of the
coreinfo features / modules will consume (trivial).

The measurements were done with libpayload r3213 (but compiled with -Os),
and coreinfo r3211 (also compiled with -Os).

Uwe Hermann ab5b3e0d98 Add support for an "NVRAM Dump" screen in coreinfo (optional), as well as for
displaying the current date/time in the lower-right corner (optional).

Also, only build/use coreinfo modules which were selected in kconfig. This
makes coreinfo truly modular, and you can save quite a bit of ROM space
by disabling unwanted parts of coreinfo.

Finally, simplify the Makefile a bit by getting rid of MODULES (and only
using OBJECTS).

Uwe Hermann 2216d1b46a Add a recent kconfig version to coreinfo, in order to make the
supported features configurable later (currently unused). Store all
build files and results (coreinfo.elf) in build/ now.

I'm self-acking this as (though non-"trivial") it doesn't affect coreinfo
in its functionality, this is more or less a "cosmetic" change to the
build interface ("make" -> "make menuconfig && make").

This is a kconfig checkout from the Linux kernel (where kconfig is being
actively maintained) from 03/2008. The hash identifying the last commit
to kconfig is 587c90616a5b44e6ccfac38e64d4fecee51d588c.

The amount of changes to kconfig itself has been kept as small as possible
to keep the diff small and to ease updating/porting to newer kconfig versions.
The following changes were performed on the upstream Linux kconfig:

 - s/kernel/coreinfo/, and s/Linux/coreinfo/ in various strings.

 - Consistently use the env. variable KERNELVERSION in all kconfig
   interfaces -- e.g. config/menuconfig/gconfig/xconfig -- as version number.

 - Hardcode our paths/filenames in some places (could be improved upstream).

 - Always write .config and build/config.h, no matter which kconfig
   interface is used (config/menuconfig/gconfig/xconfig). We want to
   include build/config.h in our code.

 - Adapt the kconfig Makefile for our purposes (build/ directory, rules, etc).

In addition, a few items in the coreinfo Makefile are needed for this to work.

This kconfig setup is successfully tested with all targets from 'make help':

  config          - Update current config utilising a line-oriented program
  menuconfig      - Update current config utilising a menu based program
  xconfig         - Update current config utilising a QT based front-end
  gconfig         - Update current config utilising a GTK based front-end
  oldconfig       - Update current config utilising a provided .config as base
  silentoldconfig - Same as oldconfig, but quietly
  randconfig      - New config with random answer to all options
  defconfig       - New config with default answer to all options
  allmodconfig    - New config selecting modules when possible
  allyesconfig    - New config where all options are accepted with yes
  allnoconfig     - New config where all options are answered with no

For 'make defconfig' to work you have to do (which we don't need in coreinfo):

  $ mkdir configs; touch configs/defconfig

You can also use 'make foo_defconfig' in which case kconfig will use a
file called 'configs/foo_defconfig' as basis.
