[coreboot] AMD G-Series SoC ("Kabini") and Olive Hill Development Board

[Bruce Griffith]

Support for AMD's latest G-Series system-on-chip (SoC) family of x86
processors has been fully released into the coreboot community.  I very
much appreciate everyone who contributed comments on the early code posted
to Gerrit, specifically Kyösti, Paul, Ron, Stepan, and the folks at Sage.
I think I have addressed all of the comments that I can to-date.  Shoot me
an e-mail if there’s something I missed.  Please review any of the code
that interests you and post comments.

The set of patches for this release include the following:

Platform Initialization (AGESA):

The AGESA/PI code is a dump from AMD’s internal BIOS team and therefore
   doesn’t necessarily meet coreboot.org standards.  The hope is that this
   one will see more regular updates than previous releases.

AGESA Wrapper code for the Family 16 (“Kabini”) CPU

AGESA Wrapper code for the Family 16 (“Kabini”) northbridge / graphics

AGESA Wrapper code modifications to Hudson code for the integrated
southbridge (“Yangtze”)

480b69a AMD Kabini: Modify Hudson southbridge to support new AMD
processor
           (http://review.coreboot.org/#/c/3783)
   d7cc030 AMD Hudson/Yangtze: Enable support for SATA port multipliers
           (http://review.coreboot.org/#/c/3808/)
   d71234f AMD Hudson: Add wrapper functions to enable LPC Super I/O ports
           (http://review.coreboot.org/#/c/3842/)
           Note: The original code in early_setup.c was used during
                 Kabini/Yangtze development.  It is not used on Olive
Hill.
                 By splitting it out as a separate changelist, the hope is
                 that it will be useful on future AMD-based boards that
                 have Super I/O chips.
