From c75c8c15b99b5045caa77b2447cfff69b725576c Mon Sep 17 00:00:00 2001 From: Felix Held Date: Tue, 13 Jul 2021 02:00:55 +0200 Subject: soc/intel/common/block/cpu/cpulib: use mca_get_bank_count() Use the common mca_get_bank_count function instead of open-coding the functionality to get the MCA bank number. Also re-type the num_banks variable from signed in to unsigned int, since the number of MCA bank is always positive, and make it constant.
