[Skiboot] [PATCH V6 08/15] core/pldm: Create boot progress and terminus locator in the given repo
Christophe Lombard
clombard at linux.ibm.com
Tue Aug 29 19:24:02 AEST 2023
The boot progress record will be used to report Opal's progress to the BMC
during the boot.
The Terminus Locator PDR forms the association between a TID and PLDM
Terminus Handle for a terminus.
This patch allows to add terminus locator record in the repository.
