From d3a6302a7317f398849cddf686705ada9353f5b6 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Sat, 28 Oct 2017 13:28:08 +0100 Subject: Silicon/Socionext: add PlatformPeilib implementation for SynQuacer 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.
