Sol Boucher 023e829423 fmaptool: Add listing of annotated CBFS sections and generate header
The fmd compiler now processes "(CBFS)" annotations, distilling them
into a comma-separated list of the names of sections containing
CBFSes. This list is the only thing printed to standard output to
enable easy capture and machine consumption by other tools.
Additionally, the ability to generate a tiny header with a define for
the primary CBFS's size is implemented and can be requested via a
new command-line switch.

Here's an example of how to use the new features:
 $ ./fmaptool -h layout.h layout_arm_8192.fmd layout.fmap 2>/dev/null
 FW_MAIN_A,FW_MAIN_B,COREBOOT
The hypothetical fmd file contains three sections annotated as (CBFS),
the names of which are printed to standard output. As before, a binary
FMAP file named layout.fmap is created; however, because the command
was invoked with -h, a header #define ing the offset of its FMAP
section (i.e. where it will be relative to the base of flash once the
boot image is assembled) is also generated.

BUG=chromium:470407
TEST=Verify that fmd files without a "COREBOOT" section or with one
that isn't annotated as "(CBFS)" are not accepted. Ensure that the
list of CBFS sections matches the descriptor file's annotations and
is led by the "COREBOOT" section. Invoke with the header generation
switch and check that output file for reasonableness.
BRANCH=None

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:
