mb/google/peppy: add _DSD to touchscreen ACPI Recent changes to the Atmel touchscreen driver in the mainline kernel broke functionality with devices running upstream coreboot, due relying on another driver (chromeos_laptop) which makes the assumption that the i2c devices are be in PCI mode (as with the stock Google firmware) rather than in ACPI mode as they are in upstream coreboot. Mitigate this by adding the required devicetree property so the Atmel toushcreen driver will correctly attach without the use of chromeos_laptop. Test: build/boot peppy on 4.18+ kernel, verify touchscreen working Change-Id: I05df8367886eef55b409590f75a68d98d4e5fbdf Signed-off-by: Matt DeVillier <matt.devillier@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/37915 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Nicolò Reviewed-by: Angel Pons <th3fanbus@gmail.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.

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.
