Ard Biesheuvel Oct. 31, 2017, 10:51 a.m.
Create a specialized PlatformPeiLib implementation that invokes the
platform specific firmware interface (currently, just a data structure
left in SRAM) to set the ARM standard PcdSystemMemoryBase|Size PCDs,
and expose the information via a newly added DramInfo PPI.

It is also in charge of copying the secondary compressed firmware
volume to DRAM before decompressing it. This works around a performance
issue regarding mapping the NOR flash with normal uncached attributes.
