>From d371dbdef635b57d993bda428a9eb6b929f4472d Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 7 Oct 2019 10:43:00 +0200 Subject: [PATCH] x86/boot: Provide memzero_explicit The purgatory code now uses the shared lib/crypto/sha256.c sha256 implementation. This needs memzero_explicit, implement this.
