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.

------------------------------------------------------------------------------- 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: http://www.coreboot.org/Mailinglist Copyright and License --------------------- The copyright on coreboot is owned by quite a large number of individual developers and companies.
