Hung-Te Lin ad173ea70b console: Revise serial console configuration names.
The console drivers (especially serial drivers) in Kconfig were named in
different styles. This change will rename configuration names to a better naming
style.

 - EARLY_CONSOLE:
        Enable output in pre-ram stage. (Renamed from EARLY_SERIAL_CONSOLE
        because it also supports non-serial)

 - CONSOLE_SERIAL:
        Enable serial output console, from one of the serial drivers. (Renamed
        from SERIAL_CONSOLE because other non-serial drivers are named as
        CONSOLE_XXX like CONSOLE_CBMEM)

 - CONSOLE_SERIAL_UART:
	Device-specific UART driver. (Renamed from
	CONSOLE_SERIAL_NONSTANDARD_MEM because it may be not memory-mapped)

 - HAVE_UART_SPECIAL:
        A dependency for CONSOLE_SERIAL_UART.

Verified to boot on x86/qemu and armv7/snow, and still seeing console
messages in romstage for both platforms.

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

coreboot is a Free Software project aimed at replacing the proprietary BIOS
(firmware) found in most computers.  coreboot performs a little bit of
hardware initialization and then executes additional boot logic, called a
payload.

With the separation of hardware initialization and later boot logic,
coreboot can scale from specialized applications that run directly
firmware, run operating systems in flash, load custom
bootloaders, or implement firmware standards, like PC BIOS services or
UEFI. This allows for systems to only include the features necessary
in the target application, reducing the amount of code and flash space
required.

coreboot was formerly known as LinuxBIOS.


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

Optional:

 * doxygen (for generating/viewing documentation)
 * iasl (for targets with ACPI support)
 * gdb (for better debugging facilities on some targets)
 * ncurses (for 'make menuconfig')
 * flex and bison (for regenerating parsers)


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

Please consult http://www.coreboot.org/Build_HOWTO 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:

  http://www.coreboot.org

You can contact us directly on the coreboot mailing list:
