From eb3c9913dc3d010e9459054e2ce2cd6a93e22a21 Mon Sep 17 00:00:00 2001 From: Alexandru Gagniuc Date: Sat, 29 Mar 2014 13:01:11 -0500 Subject: x86/Makefile: Allow addition of link libraries for rom/ramstage This is useful, for example, when using stage-independent code, as it allows us to compile that code only once. It's also useful for vendor code which needs wonky compiler definitions and include paths which we'd rather not include in the other files. Subsequent patches will make use of this when lib-izing AGESA.
