From 0a4457ff44b10f22b711f64e88888c757fbedf32 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Thu, 1 Aug 2019 20:29:14 +0300 Subject: lib/stage_cache: Refactor Kconfig options MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add explicit CBMEM_STAGE_CACHE option. Rename CACHE_RELOCATED_RAMSTAGE_OUTSIDE_CBMEM to TSEG_STAGE_CACHE. Platforms with SMM_TSEG=y always need to implement stage_cache_external_region(). It is allowed to return with a region of size 0 to effectively disable the cache. There are no provisions in Kconfig to degrade from TSEG_STAGE_CACHE to CBMEM_STAGE_CACHE. As a security measure CBMEM_STAGE_CACHE default is changed to disabled. AGESA platforms without TSEG will experience slower S3 resume speed unless they explicitly select the option.
