From 1eecd462ae052cbb056de2d89419f445c4cbd4fa Mon Sep 17 00:00:00 2001 From: Norbert Lange Date: Tue, 24 Oct 2017 14:22:06 +0200 Subject: [PATCH] arch: add Atom CPUs as Silvermont Architecture target The old Atom target is not really fitting for recent Atom CPUs based on Silvermont, Airmont or Goldmont. Those have more in common with older Desktop CPUs than old Atoms.
