[Skiboot] [PATCH v3 2/9] core/pldm/test : Initialize pldm file I/O test

Wed May 18 17:42:57 AEST 2022


The patch contains a self-test implementation for
PLDM_OEM type message support that is used for
inband file I/O.

This patch tests code flow for the PLDM command
PLDM_GET_FILE_TABLE that is used to retrieve the
file table which contains the list of lid files
available and their attributes.
