From 9b7ae2f3fccd9fd568dbc33b91bec8a0162754ee Mon Sep 17 00:00:00 2001 From: Peter Lemenkov Date: Tue, 9 Oct 2018 13:09:07 +0200 Subject: mb/lenovo/*/romstage: Use macros instead of magic numbers Apparently coreboot still uses magic numbers instead of macros in some Lenovo mainboards. Let's use macros instead. Also removed FDD from l520 romstage (original value, 0x3c0c, means that FDD_LPC_EN was also enabled).
