Combine four patches dependencies. These will not build individually, so combine them for coreboot.org upstream. samus: Move SPD handling to separate file The code to find the SPD data for the mainboard based on GPIOs is moved from romstage.c into spd.c. It relies on the updated pei_data structure from broadwell instead of the haswell interface. BUG=chrome-os-partner:28234 TEST=Build and boot on samus CQ-DEPEND=CL:199921 CQ-DEPEND=CL:199922 CQ-DEPEND=CL:199923 CQ-DEPEND=CL:199943 CQ-DEPEND=CL:*163751 Original-Change-Id: I5bd56f81884dae117b35a1ffa5fb6e804fd3cb9c Original-Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Original-Reviewed-on: https://chromium-review.googlesource.com/199920 Original-Reviewed-by: Aaron Durbin <adurbin@chromium.org> (cherry picked from commit 0bd2de4ba5eb8ba5e9d43f8e82ce9ff7587eab62) Signed-off-by: Marc Jones <marc.jones@se-eng.com> samus: Move PEI data structure init to separate file This needs to be executed in both romstage and ramstage for the different PEI binary stages. It uses the broadwell interface now instead of haswell.

There is no traditional SPD so instead one is created by hand from the provided datasheets. These have varying (and sometimes unexpected) geometry and it can be important during bringup to know what configuration is being passed to the memory training code. This could in theory be put in a more generic location, but for now this is the only board with LPDDR3 where I have found it valuable. BUG=chrome-os-partner:28234 TEST=Build and boot on samus, look for SPD details on the console.

------------------------------------------------------------------------------- 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 http://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: * http://www.coreboot.org/Supported_Motherboards * http://www.coreboot.org/Supported_Chipsets_and_Devices Build Requirements ------------------ * gcc / g++ * make Optional: * doxygen (for generating/viewing documentation) * iasl (for targets with ACPI support) * gdb (for better debugging facilities on some targets) * ncurses (for 'make menuconfig') * flex and bison (for regenerating parsers) Building coreboot ----------------- Please consult http://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 http://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: http://www.coreboot.org You can contact us directly on the coreboot mailing list: http://www.coreboot.org/Mailinglist Copyright and License --------------------- The copyright on coreboot is owned by quite a large number of individual developers and companies.
