From 513a1a81f778b9fddbb55a36a38b2dd855215327 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Sun, 3 Jun 2018 12:29:50 +0300 Subject: arch/x86 cbmem: Drop tests for LATE_CBMEM_INIT MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Remove all cases in code where we tested for EARLY_CBMEM_INIT or LATE_CBMEM_INIT being set. This also removes all references to LATE_CBMEM_INIT in comments.
