From f437c24bf694b0293f835dea8c25e3a5c1433d07 Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Tue, 16 Jan 2018 22:30:40 +0200 Subject: thunderbolt: Move NVM upgrade support flag to struct icm This is depends on the controller and on the platform/CPU we are running. Move it to struct icm so we can set it per controller.
