Uwe Hermann 63a8f2a7c2 Add kconfig menus for most chipset VIDEO_MB values.
VIDEO_MB is a variable that defines how many MB of RAM will be used
for onboard graphics frame buffer. It's northbridge-dependent which
values for CONFIG_MB are valid (but not board-dependent).

This patch adds choices for menuconfig to select the VIDEO_MB value for:

 - Intel 82810
 - Intel 82830
 - VIA CN400
 - VIA CN700

Note: CN400 and CN700 are based on the CX700 datasheet, not sure if they're
correct. If somebody has CN400 and CN700 datasheets, please verify.

We drop all per-board VIDEO_MB variables in per-board Kconfig files as
there's a northbridge-specific option/default now (plus the user can override
the value if needed in menuconfig).

As CONFIG_MB is chipset-specific but not board-specific (and never was), filter
it in util/compareboard/compareboard, we don't need to match those values.

Finally, put "CPU", "Northbridge", "Southbridge", "Super I/O", and
"Devices" sections into the "Chipset" menu, where NB-specific
options will appear if you select a board using a certain NB,
SB-specific options would appear in the "Southbridge" section etc.

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:
