Duncan Laurie 2663a55caf samus: Combine mainboard patches to build soc/intel/broadwell
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.

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.

samus: Convert mainboard to use soc/intel/broadwell

Switch from the haswell cpu/northbridge/southbridge interface
to the soc/intel/broadwell interface.

- Use new headers where appropriate
- Remove code that is now done by the SOC generic code
- Update GPIO map to drop LP specific handling
- Update INT15 handlers, drop all but the boot display hook

samus: Add some code to print basic info from SPD

The handling of LPDDR is a bit messy in Intel platforms.  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:
