commit 38cd64645b8364b20ce64c71a3ba5caff5675955 Author: Kyösti Mälkki kyosti.malkki@gmail.com Date: Thu Mar 2 13:52:54 2017 +0200
AGESA: Make eventlog more tolerant to failures
We have been forced to build AGESA with ASSERT() as non-fatal for some board, as hitting those errors is not uncommon.
For the cases touched here, abort eventlog operations early with null pointers and errors.
