soc/{apl,glk}: Allow to select the primary graphics device Allow to select the primary graphics device between the IGD and the external PCIe GPU depending on the ONBOARD_VGA_IS_PRIMARY config. The option sets the priority only. This means that if a high priority is set for an external PCI device and it is not connected/not enabled, then the device with a lower priority will be used, in our case it is IGD. TEST = Set PRIMARY_PCI and boot Linux on the Kontron mAL10 [1] with the miniPCIe video adapter on the Silicon Motion SM750 controller. As a result, the display connected to an external GPU device shows the Tianocore logo + setup menu and the desktop.

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.
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.
coreboot supports a wide range of chipsets, devices, and mainboards.

ANY_TOOLCHAIN
Kconfig option if you're feeling lucky (no support in this case).Optional:
make menuconfig
and make nconfig
)Please consult https://www.coreboot.org/Build_HOWTO for details.
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.
Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website:
