From 45eeae4f8f3846a44b48b4334988e94c2776898d Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Tue, 10 Nov 2020 16:57:44 +0100 Subject: mb/siemens/mc_apl1: Deduplicate wait_for_legacy_dev() There's one copy of this function for all variants except mc_apl4. Move one copy into common mainboard.c and exit early if running on mc_apl4.
