From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Peter Jones Date: Mon, 15 Feb 2021 14:21:48 +0100 Subject: [PATCH] util/mkimage: Reorder PE optional header fields set-up This makes the PE32 and PE32+ header fields set-up easier to follow by setting them closer to the initialization of their related sections.
