[edk2] [PATCH v1 09/22] DynamicTablesPkg: Configuration Manager Protocol

Sami Mujawar sami.mujawar at arm.com
Fri Dec 21 08:57:06 PST 2018


Introduce configuration manager protocol interface
that is used by the dynamic tables framework core
to communicate with configuration manager.

Configuration manager is a platform specific module
that implements the configuration manager protocol.

Table generators use this interface to retrieve the
hardware information from the configuration manager.
