UPSTREAM: drivers/mipi: Modify INX_P110ZZD_DF0 panel initialization code There is a problem of screen shake on the old panel[1]. So increase the panel GOP component pull-down circuit size in hardware, and update the initialization code at the same time. The new initialization code is mainly adjusted for GOP timing. When Display sleep in, raise all GOP signals to VGHO and then drop to GND. In order to be consistent with the current panel model, let's rename this file. [1]: INX old panel product number is HJ110IZ-01A-B1, and the new panel product number is HJ110IZ-01A-B2. We have recalled the shipment old panel.

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.
Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website:
