intel: Drop FSP_PEIM_TO_PEIM_INTERFACE

This change drops the config FSP_PEIM_TO_PEIM_INTERFACE.

FSP_PEIM_TO_PEIM_INTERFACE is used for:
* Auto-selecting FSP_USES_MP_SERVICES_PPI
* Including src/drivers/intel/fsp2_0/ppi/Kconfig
* Adding ppi to subdirs-y
* Setting USE_INTEL_FSP_TO_CALL_COREBOOT_PUBLISH_MP_PPI to y

and is selected by SoCs that want to enable MP PPI services.

Instead of using the indirect path of selecting MP PPI services, this
change allows SoC to select FSP_USES_MP_SERVICES_PPI directly. The
above uses are handled as follows:

* Auto-selecting FSP_USES_MP_SERVICES_PPI
  --> This is handled by SoC selection of FSP_USES_MP_SERVICES_PPI.
* Including src/drivers/intel/fsp2_0/ppi/Kconfig
  --> The guard isn't really required. The Kconfig options in this
  file don't present user prompts and don't really need to be guarded.
* Adding ppi to subdirs-y
  --> Makefile under ppi/ already has conditional inclusion of files
  and does not require a top-level conditional.
* Setting USE_INTEL_FSP_TO_CALL_COREBOOT_PUBLISH_MP_PPI to y
  --> This is set to y if FSP_USES_MP_SERVICES_PPI is selected by SoC.

TEST=Verified that timeless build for brya, volteer, icelake_rvp,
elkhartlake_crb and waddledee shows no change in generated coreboot.rom

coreboot README

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.

Payloads

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.

Supported Hardware

coreboot supports a wide range of chipsets, devices, and mainboards.

For details please consult:

Build Requirements

  • make
  • gcc / g++ Because Linux distribution compilers tend to use lots of patches. coreboot does lots of "unusual" things in its build system, some of which break due to those patches, sometimes by gcc aborting, sometimes - and that's worse - by generating broken object code. Two options: use our toolchain (eg. make crosstools-i386) or enable the ANY_TOOLCHAIN Kconfig option if you're feeling lucky (no support in this case).
  • iasl (for targets with ACPI support)
  • pkg-config
  • libssl-dev (openssl)

Optional:

  • doxygen (for generating/viewing documentation)
  • gdb (for better debugging facilities on some targets)
  • ncurses (for make menuconfig and make nconfig)
  • flex and bison (for regenerating parsers)

Building coreboot

Please consult https://www.coreboot.org/Build_HOWTO for details.

Testing coreboot Without Modifying Your Hardware

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.

Website and Mailing List

Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website:
