From 8984af89b85034ad0456bb3a63a78cd63c618934 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Tue, 19 Apr 2016 17:06:09 -0500 Subject: lib: add helper for constructing coreboot forwarding table The x86 architecture needs to add a forwarding table to the real coreboot table. Provide a helper function to do this for aligning the architectures on a common write_tables() implementation.
