Platform/ARM: Dynamic Tables support for Juno
The dynamic tables framework utilizes the configuration manager
protocol to get the platform specific information required for
building the firmware tables.
The configuration manager is a platform specific component that
collates the platform hardware information and builds an abstract
platform configuration repository. The configuration manager also
implements the configuration manager protocol which returns the
hardware information requested by the table generators.
This patch implements the configuration manager support for the
Juno platform.
The dynamic tables framework support is configurable and can be
enabled using the DYNAMIC_TABLES_FRAMEWORK build option.
When DYNAMIC_TABLES_FRAMEWORK is defined, ACPI tables are generated
and installed by the dynamic table framework. Therefore installation
of ACPI tables from the Firmware Volume (FV) is disabled by this
option.
