This library follows the code update design: https://github.com/openbmc/docs/blob/master/designs/code-update.md
It enables implementing code updaters for different devices. Each one inherits from the classes found in the common folder.
Device-specific class members can be added to implement the code update flow for different devices.
To understand the control flow, consider looking at 'NopDevice' and 'NopDeviceCodeUpdater'.
They implement a complete device-specific code updater, for the nop device, which is a nonexistent device used only for examples and testing.
It implements everything expected of a device-specific code updater and can be used as a starting point.
The PackageParser in the pldm directory currently references a following revision from the openbmc/pldm repository -
However, this code will be deprecated and replaced with the package parsing APIs provided by libpldm once they become available.
The PackageParser has a maximum supported PLDM firmware package revision of 1.0.0.
