From cf58b2d41cb0d24239b98de98264b31690711549 Mon Sep 17 00:00:00 2001 From: Boyan Karatotev Date: Tue, 25 Oct 2022 11:29:04 +0100 Subject: [PATCH] chore: rename Makalu ELP to Cortex-X3 The Cortex-X3 cpu port was developed before its public release when it was known as Makalu ELP. Now that it's released we can use the official product name.
