From 537b4e09e644107ed644cd88f8a7fd488406b9a2 Mon Sep 17 00:00:00 2001 From: Vadim Bendebury Date: Tue, 19 Jun 2012 12:56:57 -0700 Subject: Add code to read Intel microcode from CBFS When CONFIG_MICROCODE_IN_CBFS is enabled, find the microcode blob in CBFS and pass it to intel_update_microcode() instead of using the compiled in array. CBFS accesses in pre-RAM and 'normal' environments are provided through different API.
