From 7c19e50bdd3b6ae234b171992f2e109d4f804cda Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Tue, 18 Dec 2018 08:45:06 +0100 Subject: score: Fix per-CPU data allocation Allocate the per-CPU data for secondary processors directly from the heap areas before heap initialization and not via _Workspace_Allocate_aligned(). This avoids dependency on the workspace allocator. It fixes also a problem on some platforms (e.g. QorIQ) where at this early point in the system initialization the top of the RAM is used by low-level startup code on secondary processors (boot pages).
