From 3b2e4f542e3ea5d116d5830f4eef9be97d872312 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 27 Aug 2024 19:44:25 -0600 Subject: x86: Ensure the CPU identity exists for timer init When bootstage is used the timer can be inited before the CPU identity is set up, resulting in the checks for the vendor not working. Add a special call to work around this.
