New Revision: 6555
URL: https://tracker.coreboot.org/trac/coreboot/changeset/6555
Log:
Remove AMD Agesa requirement for standard include files
This change modifies Makefile.inc to add the -nostdinc flag to the default
CFLAGS value and removes the test for non-AMD Agesa builds. Other code is
added to the gcc-intrin.h file in the Agesa Include folder to make the
requirement for the standard includes obsolete from the Agesa perspective.
