From 5efee3a2c28aa7e53074288733632fa06ac66046 Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Sun, 13 Oct 2019 23:04:19 +0200 Subject: soc/intel/broadwell: Don't reinitialize SPI after lockdown With the common southbridge SPI code reinitialization after lockdown is not necessary, hence the SMM finalize call becomes a no-op.
