From fb39f82116f0411ee85e3d91bfd97237c34debbb Mon Sep 17 00:00:00 2001 From: Timothy Pearson Date: Tue, 2 Jun 2015 20:25:03 -0500 Subject: cpu/amd/car: Move AP stacks below the BSP stack to free up space Caching SPD data during startup requires additional CAR space. There was a large chunk of free space between the AP stack top and the BSP stack bottom; moving the AP stacks below the BSP stack allows this space to be utilized. TEST: Booted ASUS KGPE-D16 with dual Opteron 6129 processors (16 cores) and 120k of CAR.
