Uwe Hermann 168b11bc41 Various Kconfig fixes and improvements:
- Add helps texts to multiple user-visible Kconfig options.

 - Improve some menu and option names.

 - PAYLOAD_NONE should come before PAYLOAD_ELF, so that you scroll down
   (instead of up) when changing "no payload" to "ELF payload" (more
   intuitive, IMHO).

 - s/cbfs/cbfstool/.

 - Add some TODO items where needed.

 - Put GDB_STUB in a "Debugging" menu, no options should be top-level.
   There'll be more debug options later, I'm pretty sure.

 - Start converting help texts which are not user-visible to #-comments.

 - Re-order some options for more intuitive menus.

 - Set ARCH_X86 and ARCH_POWERPC to "default n", each boards selects them.

 - "Maximum reboot count" should proabably not be user-selectable, or at
   most if CONFIG_EXPERT (yet to be added) is enabled. It does definately
   not need its own "Misc options" menu.

 - Set PCI_ROM_RUN and VGA_ROM_RUN to "default y", most users will want to
   run option ROMs.

README

-------------------------------------------------------------------------------
coreboot README
-------------------------------------------------------------------------------

coreboot is a Free Software project aimed at replacing the proprietary
BIOS you can find in most of today's computers.

It performs just a little bit of hardware initialization and then executes
one of many possible payloads, e.g. a Linux kernel or a bootloader.


Payloads
--------

After the basic initialization of the hardware has been performed, any
desired "payload" can be started by coreboot.

See http://www.coreboot.org/Payloads for a list of supported payloads.


Supported Hardware
------------------

coreboot supports a wide range of chipsets, devices, and mainboards.

For details please consult:

 * http://www.coreboot.org/Supported_Motherboards
 * http://www.coreboot.org/Supported_Chipsets_and_Devices


Build Requirements
------------------

 * gcc / g++
 * make
 * python
 * perl

Optional:

 * doxygen (for generating/viewing documentation)
 * iasl (for targets with ACPI support)
 * gdb (for better debugging facilities on some targets)


Building coreboot
-----------------

Please consult http://www.coreboot.org/Documentation for details.


Testing coreboot Without Modifying Your Hardware
-------------------------------------------------

If you want to test coreboot without any risks before you really decide
to use it on your hardware, you can use the QEMU system emulator to run
coreboot virtually in QEMU.

Please see http://www.coreboot.org/QEMU for details.


Website and Mailing List
------------------------

Further details on the project, a FAQ, many HOWTOs, news, development
guidelines and more can be found on the coreboot website:
