mb/google/zork: Add helpers for v3 schematics and wifi power enable This change adds following two helper functions: 1. variant_uses_v3_schematics() - Check whether the variant is using v3 version of schematics. 2. variant_has_active_low_wifi_power() - Check whether the variant is using active low power enable for WiFi. In addition to this, Kconfig options are reorganized to add two new configs - VARIANT_SUPPORTS_PRE_V3_SCHEMATICS and VARIANT_SUPPORTS_WIFI_POWER_ACTIVE_HIGH. This allows the helper functions to return `true` early without checking for board version. Eventually, when a variant decides to drop support for pre-v3 schematics, it can be dropped from selecting VARIANT_SUPPORTS_PRE_V3_SCHEMATICS. Similarly, when the variant decides to drop support for active high power enable for WiFi, it can be dropped from selecting VARIANT_SUPPORTS_WIFI_POWER_ACTIVE_HIGH.

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.
For details please consult:
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.
