vboot: refactor OPROM code The name OPROM is somewhat inaccurate, since other steps to bring up display and graphics are needed depending on mainboard/SoC. This patch cleans up OPROM code nomenclature, and works towards the goal of deprecating vboot1: * Rename CONFIG_VBOOT_OPROM_MATTERS to CONFIG_VBOOT_MUST_REQUEST_DISPLAY and clarify Kconfig description * Remove function vboot_handoff_skip_display_init * Remove use of the VbInit oflag VB_INIT_OUT_ENABLE_DISPLAY * Add |flags| field to vboot_working_data struct * Create VBOOT_FLAG_DISPLAY_REQUESTED and set in vboot_handoff BUG=b:124141368, b:124192753, chromium:948529 TEST=make clean && make test-abuild TEST=build and flash eve device; attempt loading dev/rec modes BRANCH=none Change-Id: Idf111a533c3953448b4b9084885a9a65a2432a8b Signed-off-by: Joel Kitching <kitching@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/32262 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Julius Werner <jwerner@chromium.org>
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:
