soc/intel/common/block/p2sb: Refactor P2SB to add comprehend future SoC This patch refactors the current P2SB common code driver to accommodate the future SoC platform with provision of more than one P2SB IP in disaggregated die architecture. IA SoC has only one P2SB in PCH die between SKL to ADL. Starting with MTL, one more P2SB IP resides in IOE die along with SoC die. (PCH die is renamed as SoC in MTL.) P2SB library (p2sblib.c) is common between PCH/SoC and IOE, and p2sb.c is added only for PCH/SoC P2SB. BUG=b:224325352 TEST=Able to build and boot brya.

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:
