> Subject: [PATCH 2/2][platforms/dynamictables] Platform/ARM: Dynamic
> Tables support for FVP
> 
> 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.
