From 340e4b80904feb6c5c21497fc52966854fa5ee79 Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Wed, 23 Oct 2019 17:25:58 +0200 Subject: lib/cbmem_top: Add a common cbmem_top implementation This adds a common cbmem_top implementation to all coreboot target. In romstage a static variable will be used to cache the result of cbmem_top_romstage. In ramstage if CONFIG_RAMSTAGE_CBMEM_TOP_ARG is set a global variable needs to be populated by the stage entry with the value passed via the calling arguments. if CONFIG_RAMSTAGE_CBMEM_TOP_ARG is not set the same implementation as will be used as in romstage.
