[PATCH edk2-platforms v1 2/6] Platform/ARM: Dynamic Tables support for Juno

[Sami Mujawar <sami.mujawar@arm.com>]

The dynamic tables framework uses the platform hardware
information described by the configuration manager to
generate ACPI tables. This 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.
