From c6efb7a42dddd374f934cc217e6c7f5f6cadfa18 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 29 Sep 2024 19:49:30 -0600 Subject: scripts: Rename Makefile.spl to Makefile.xpl Rename this file to indicate that it refers to any non-U-Boot-proper phase, not just SPL, which is the phase immediately before U-Boot proper.
