Ren Kuo 163dfe68f6 mb/google/dedede/var/magolor: Modify SSFC for camera and touchscreen
The all shipped magolor and maglia has SSFC= 0x840.
The value is defined as 5M MIPI camera.But the value:0x840 will
conflict with the updated touchscreen field.
It will cause some touchscreen no function if make auto-update new
firmware.The CL would correct the field error.

The original fields:
CAMERA_WFC 38 40
TS_SOURCE  41 44

Correct fields:
MIPI Cam
  CAMERA_WFC 38 40
  CAMERA_UFC 41 42
  CAMERA_VCM 43 44
Touch-screen
  TS_SOURCE  45 48

The SSFC value of Magolor:
CAMERA_OVTI5675  5M AF (SSFC = 0x840)
CAMERA_OVTI8856  8M AF (SSFC = 0x880)

BUG=b:194639170
TEST=Build firmware and verify on camera and touch-screen devices

coreboot README

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.

Payloads

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.

Supported Hardware

coreboot supports a wide range of chipsets, devices, and mainboards.

For details please consult:

Build Requirements

  • make
  • gcc / g++ Because Linux distribution compilers tend to use lots of patches. coreboot does lots of "unusual" things in its build system, some of which break due to those patches, sometimes by gcc aborting, sometimes - and that's worse - by generating broken object code. Two options: use our toolchain (eg. make crosstools-i386) or enable the ANY_TOOLCHAIN Kconfig option if you're feeling lucky (no support in this case).
  • iasl (for targets with ACPI support)
  • pkg-config
  • libssl-dev (openssl)

Optional:

  • doxygen (for generating/viewing documentation)
  • gdb (for better debugging facilities on some targets)
  • ncurses (for make menuconfig and make nconfig)
  • flex and bison (for regenerating parsers)

Building coreboot

Please consult https://www.coreboot.org/Build_HOWTO for details.

Testing coreboot Without Modifying Your Hardware

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.

Website and Mailing List

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