mb/google/guybrush: Enable SOC_AMD_COMMON_BLOCK_I2C3_TPM_SHARED_WITH_PSP Guybrush platforms have I2C3 controller which is shared between PSP and X86. In order to enable cooperation, PSP acts as an arbitrator. Enable SOC_AMD_COMMON_BLOCK_I2C3_TPM_SHARED_WITH_PSP, so that proper driver is binded on the OS side. With this change in place it is important to use correct kernel version which has I2C-amdpsp driver [1] enabled. Otherwise, we won't have I2C3 available and thus TPM device available in OS, what may end up as a serious error - guybrush refuses to boot without access to TPM. BUG=b:204508404 BRANCH=guybrush TEST=Build proper kernel and firmware. Run on guybrush and verify TPM functionality.

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.
For details please consult:
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:
