From 95de2317c6c6379e43d3b3c27d34eb66198dbe0a Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Mon, 17 Feb 2020 13:08:53 +0100 Subject: nb/intel/nehalem: Rename to ironlake The code is for Arrandale CPUs, whose System Agent is Ironlake. This change simply replaces `nehalem` with `ironlake` and `NEHALEM` with `IRONLAKE`. The remaining `Nehalem` cases are handled later, as changing some of them would impact the resulting binary. Tested with BUILD_TIMELESS=1 without adding the configuration options into the binary, and packardbell/ms2290 does not change.
