soc/intel/common/block/pcie/rtd3: Update ACPI methods for CPU PCIe RPs The PMC IPC method that is used for RTD3 support expects to be provided the virtual wire index instead of the LCAP PN for CPU PCIe RPs. Therefore, use the prior patches to update pcie_rp for CPU RPs. Note that an unused argument to pcie_rtd3_acpi_method_status() was also dropped. BUG=b:197983574 TEST=add rtd3 node under pcie4_0 in overridetree for brya0, boot and inspect the SSDT to see the PMC IPC parameters are as expected for the CPU RP, and the ModPhy power gating code is not found in the AML for the PEG port.

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:
