From b1b44d34e39e52edfe5521d0671d685962529885 Mon Sep 17 00:00:00 2001 From: Rizwan Qureshi Date: Fri, 26 Aug 2016 21:08:50 +0530 Subject: arch/x86: Always compile postcar library in romstage postcar_loader.c has a useful library of funtions for setting up stack and MTRRs. Make it available in romstage irrespective of CONFIG_POSTCAR_STAGE for use in stack setup after Dram init. The final step of moving the used and max MTRRs on to stack is moved to a new function, that can be used outside of postcar phase.
