This patch renames all FSP Notify Phase API configs to primarily remove "SKIP_" prefix. 1. SKIP_FSP_NOTIFY_PHASE_AFTER_PCI_ENUM -> USE_FSP_NOTIFY_PHASE_POST_PCI_ENUM 2. SKIP_FSP_NOTIFY_PHASE_READY_TO_BOOT -> USE_FSP_NOTIFY_PHASE_READY_TO_BOOT 3. SKIP_FSP_NOTIFY_PHASE_END_OF_FIRMWARE -> USE_FSP_NOTIFY_PHASE_END_OF_FIRMWARE The idea here is to let SoC selects all required FSP configs to execute FSP Notify Phase APIs unless SoC deselects those configs to run native coreboot implementation as part of the `.final` ops. For now all SoC that uses FSP APIs have selected all required configs to let FSP to execute Notify Phase APIs. Note: coreboot native implementation to skip FSP notify phase API (post pci enumeration) is still WIP. Additionally, fixed SoC configs inclusion order alphabetically.

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 https://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:
Build Requirements
- make
- gcc / g++
Because Linux distribution compilers tend to use lots of patches. coreboot
does lots of "unusual" things in its build system, some of which break due
to those patches, sometimes by gcc aborting, sometimes - and that's worse -
by generating broken object code.
Two options: use our toolchain (eg. make crosstools-i386) or enable the
ANY_TOOLCHAIN
Kconfig option if you're feeling lucky (no support in this case). - iasl (for targets with ACPI support)
- pkg-config
- libssl-dev (openssl)
Optional:
- doxygen (for generating/viewing documentation)
- gdb (for better debugging facilities on some targets)
- ncurses (for
make menuconfig
andmake nconfig
) - flex and bison (for regenerating parsers)
Building coreboot
Please consult https://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 https://www.coreboot.org/QEMU for details.
