Platform/ARM: Dynamic Tables support for FVPdevel-dynamictables
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 FVP platform. The dynamic tables framework support is configurable and can be enabled using the DYNAMIC_TABLES_FRAMEWORK build option.
