Subject: [edk2-devel] [edk2-platforms PATCH v1 1/1 -resend] Platfor= m/ARM/JunoPkg: Add support for PPTT dynamic generation
 
Update the Platform Respository for the Juno plat= form
to include support for generation of the Processor Properties
Topology Table (PPTT) using the Dynamic Tables Framework.

The Platform Repository now also describes the cache and
processor topology in Juno (all revisions).
