commit ec39a876e0dafef0b3cfe83b3b0df908ecfc034e Author: Kyösti Mälkki kyosti.malkki@gmail.com Date: Fri Oct 11 22:08:02 2013 +0300
Revert "CBMEM: Always have early initialisation"
This reverts commit de1fe7f655c549e8dce5b34218221890fa5ccc34.
While things appeared to work, there were actually invalid references to CAR storage after CAR was torn down on boards without EARLY_CBMEM_INIT. It was discussed use of CAR_GLOBAL should be restricted to boards that handle CAR migration properly.
