From bc17cdef0d3370f10f43ef45272399e3103eb01b Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Fri, 7 Apr 2017 15:20:14 -0500 Subject: arch/x86: remove CAR global migration when postcar stage is used MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When a platform is using postcar stage it's by definition not tearing down cache-as-ram from within romstage prior to loading ramstage. Because of this property there's no need to migrate CAR_GLOBAL variables to cbmem.
