From 5004c78ef71ce94f53c9c7ddc18f073348f4b324 Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Wed, 23 Oct 2024 18:52:35 +0200 Subject: soc/intel/xeon_sp/skx: Use Kconfig symbol Use Kconfig symbol CPU_BCLK_MHZ as done on CPX. Reduced code differences between SKX and CPX and will allow to merge the codebase into one.
