From 9f55574c907dd3c52d9078651d5cfea2f4cda4e3 Mon Sep 17 00:00:00 2001 From: Marc Jones Date: Thu, 24 Sep 2020 16:35:56 -0600 Subject: soc/intel/xeon_sp/skx/: Reorder acpi.c functions Reorder the functions to make it easier to compare with soc/intel/common/block/acpi/acpi.c and cpx/acpi.c. Move the xeon_sp specific functions to the top.
