commit f8f676cfb6d1a176feb4ffb92830c5da76a81be4 Author: Bruce Griffith Bruce.Griffith@se-eng.com Date: Sun Aug 10 23:56:45 2014 -0600
AMD Steppe Eagle: Add binary PI vendorcode files
Add all of the PI source that will remain part of coreboot to build with a binary AGESA PI BLOB. This includes the gcc makefiles, some Kconfig, and the AGESA standard library functions.
Change vendorcode Makefile and Kconfig so that they can compile AMD library files and use headers from outside the coreboot/src tree.
This fix changes the makefile so that the AGESA dispatcher is built using its own rules rather than generic library generation rules in coreboot/Makefile and coreboot/Makefile.inc. The AGESA source files are initially copied from whereever they live into coreboot/build/agesa. They are compiled from there. The binary PI directory now has a mandatory structure that places the AGESA BLOB into the same directory as the support headers. The PI headers will nominally be placed at 3rdparty/pi/amd/<processor>.
