soc/amd/psp: Add SmmInfo command Implement the MboxBiosCmdSmmInfo function to inform the PSP of the SoC's SMM configuration. Once the BootDone command is sent, the PSP only responds to commands where the buffer is in SMM memory. Set aside a region for the core-to-PSP command buffer and the PSP-to-core mailbox. Also add an SMM flag, which the PSP expects to read as non-zero during an SMI. Add calls to soc functions for the soc to populate the trigger info and register info (v2 only). Add functions to set up the structures needed for the SmmInfo function in Picasso support. Issue a SW SMI, and add a new handler to call the new PSP function.

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.
