From 5dfb3314b436fd5edf6f65112f34d7d8e3f1a162 Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Mon, 15 Feb 2021 13:08:43 +0100 Subject: cpu/x86/smm: Move relocatable stub params These stub params need to be synced with the code in smm_stub.S and are consumed by both the smmloader and smmloader_v2. So it is better to have the definition located in one place.
