From 1e162bf8bd74e8dcd0b164b627e1d536c7dbd5f5 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Fri, 6 May 2016 09:20:35 -0700 Subject: lib/prog_loaders: Allow platforms to skip stage cache Before multi-CBFS support was added, x86 platforms cached their ramstage in TSEG so that it could be re-used on the resume path. However, more resources/assets are being put in cbfs that are utilized during ramstage. Just caching ramstage does not mean that correct cbfs region is used for all the data. Thus, provide an option to allow platforms to skip caching any component for resume.
