This activates support for fit images and some other new mkimage
features. Some of the patches were applied upstream and could be
removed.

From f3f431a712729a1af94d01bd1bfde17a252ff02c Mon Sep 17 00:00:00 2001

Subject: [PATCH] Reproducible U-Boot build support, using SOURCE_DATE_EPOCH
In order to achieve reproducible builds in U-Boot, timestamps that are defined
at build-time have to be somewhat eliminated. The SOURCE_DATE_EPOCH environment
variable allows setting a fixed value for those timestamps.
Simply by setting SOURCE_DATE_EPOCH to a fixed value, a number of targets can be
built reproducibly. This is the case for e.g. sunxi devices.
However, some other devices might need some more tweaks, especially regarding
the image generation tools.

+Reproducible builds
+-------------------
+
+In order to achieve reproducible builds, timestamps used in the U-Boot build
+process have to be set to a fixed value.
+
+This is done using the SOURCE_DATE_EPOCH environment variable.
+SOURCE_DATE_EPOCH is to be set on the build host's shell, not as a configuration
+option for U-Boot or an environment variable in U-Boot.
+
+SOURCE_DATE_EPOCH should be set to a number of seconds since the epoch, in UTC.

Subject: Fix musl build

Fix musl build
This patch fixes cross-compiling U-Boot tools with the musl C library:
* including <sys/types.h> is needed for ulong
* defining _GNU_SOURCE is needed for loff_t
Tested for target at91sam9261ek_dataflash_cs3.
