mb/google/zork: Set vw_irq_polarity from low to high The EC used on zork uses a level high interrupt. This change configures the polarity correctly. The eSPI config is baked into RO verstage. The zork ToT build doesn't use signed verstage since it's incompatible with the ToT version of vboot. This means we can safely switch the keyboard IRQ polarity. NOTE: Do not cherry pick this into the Zork firmware branch! BUG=b:160595155 TEST=On morphius verify keyboard works as correctly and no spurious interrupts are thrown on S0i3 resume. Also verified keyboard and mouse work correctly in windows.

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.
