From 0b20b83b7da32fc96f41ca7fe92c920d36a05b05 Mon Sep 17 00:00:00 2001 From: Frans Hendriks Date: Tue, 1 Oct 2019 13:41:04 +0200 Subject: mb/facebook/fbg1701: Add mainboard_read_pcb_version() PCB version is determined using inb() in actual code. Create function mainboard_read_pcb_version to read pcb version.
