From: Joerg Roedel jroedel@suse.de Date: Mon, 26 Apr 2021 10:17:48 +0200 Subject: [PATCH] crypto: ccp - Annotate SEV Firmware file names
Annotate the firmware files CCP might need using MODULE_FIRMWARE(). This will get them included into an initrd when CCP is also included there. Otherwise the CCP module will not find its firmware when loaded before the root-fs is mounted. This can cause problems when the pre-loaded SEV firmware is too old to support current SEV and SEV-ES virtualization features.
