From 3fa23b8c008709e4204992c52fcd5b729454b333 Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Mon, 25 Jan 2021 09:42:08 +0100 Subject: soc/intel/*: Get rid of custom microcode caching Get rid of custom microcode caching in MPinit and SGX code and use the caching introduced in intel_microcode_find() instead.
