mb/google/volteer: Enable RTD3 for SD card Enable the PCIe RTD3 driver for the PCIe attached SD card interface and provide the enable/reset GPIOs. These GPIOs are common across all variants so this is implemented in the baseboard devicetree with an fw_config probe if the device is present. The RTS5261 device does not have an enable GPIO so it is disabled in a workaround in mainboard.c, along with marking the SD-Express device as external. BUG=b:162289926, b:162289982 TEST=Tested on Delbin platform to ensure the system can enter the S0i3.2 substate and suspend/resume is stable. enabling this for the regular Genesys Change-Id: I40fe05829783c7bce2a2c4c1520a4a7430642e26 Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/47377 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
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.

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:
