soc/intel/common/gpio: Support 4 bits GPIO pad mode configuration Intel GPIO pad supports 4 bits pad mode, PAD_CFG_DW0[13:10] for pins that native function 8 to 15 is assigned. This adds native function definitions from NF8 to NF15 and updates PAD_CFG0_MODE_MASK to support 4 bits pad mode configuration. Since PAD_CFG_DW0[16:13] is reserved for pins that NF8 or higher is not assigned, this change would not cause an issue but Kconfig option is added to minimize an impact and support 4 bits pad mode configuration.

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:
