From 9204355b4d2a7dbde41dff262f223a6b7ac674b2 Mon Sep 17 00:00:00 2001 From: Thomas Heijligen Date: Tue, 29 Jan 2019 12:48:01 +0100 Subject: string: move strdup() & strconcat() to lib/string.c Move functions not available in PRE_RAM into seperate file. Makes it easier to share code between rom and ramstage.
