From 082c19ea89a24216aafd4ef728f9983b93f6b486 Mon Sep 17 00:00:00 2001 From: Kyösti Mälkki Date: Sat, 12 Oct 2013 00:22:57 +0300 Subject: CBMEM: Fail builds on missing get_top_of_ram() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Dummy get_top_of_ram() is removed from romstage to fail already at build-time for cases where cbmem_initialize() would not complete. The mechanisms behind CAR_GLOBAL migration only work correctly when romstage can succesfully make the cbmem_initialize() call.
