From b2545cc3c6388d0328ce24a81df104a6d069e952 Mon Sep 17 00:00:00 2001 From: Rob Barnes Date: Wed, 9 Sep 2020 13:19:09 -0600 Subject: [PATCH] soc/amd/picasso: Move APCB generation out of picasso Move APCB generation out of the picasso makefile and into the mainboard makefile. APCB generation tends to be mainboard specific and does not belong in the soc makefile.
