From 4f14cd8a39e65811af08296633842289efa42927 Mon Sep 17 00:00:00 2001 From: Kyösti Mälkki Date: Wed, 18 Dec 2019 19:40:48 +0200 Subject: arch/x86,soc/intel: Drop RESET_ON_INVALID_RAMSTAGE_CACHE MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If stage cache is enabled, we should not allow S3 resume to load firmware from non-volatile memory. This also adds board reset for failing to load postcar from stage cache.
