From 855fc1fcdbf1e40931d31f25ca7091a7b0aeace5 Mon Sep 17 00:00:00 2001 From: Timothy Pearson Date: Wed, 14 Oct 2015 15:41:49 -0500 Subject: cpu/microcode: Remove EXTERNAL / ADDED_DURING_BUILD variables There has been a concerted effort to clean up coreboot's microcode handling that has included a move away from coreboot-specific microcode file collections. As a result, the ability to specify a single microcode file to be added to the image is of less utility than before. NOTE: This patch remove the built-in external microcode feature, however the user can still specify no microcode during build and manually add the correct microcode file(s) to the CBFS image after the build is complete.
