From 53485124513a76ebe85a80f59e8dff9915f518bd Mon Sep 17 00:00:00 2001 From: Rizwan Qureshi Date: Mon, 18 Jun 2018 19:50:18 +0530 Subject: Kconfig: Add config to insert ucode address in second FIT This config is used to provide the name of a region where a microcode is located. The address of this will be added as the first entry in the FIT of the topswap bootblock. This adds a capability to associate two microcodes for each of the two bootblocks, this allows for the CPU to boot with different microcodes with 2 separate bootblocks.
