Commit 02a2433c ("ti-sci-fw: Update image gen to latest") switched to a
newer commit in k3-image-gen that also picked up TISCI firmware release,
However, does include a change where the SPL address changed.

This switch in address has been queued for upstream in a future release
(v5.14 + u-boot 2021.10) and current mainline formal tags do not support
this address change. As a result, we have a broken AM64x mainline
support.

Revert this specific change from k3-image-gen for mainline alone for
now.

NOTE: This uses ARAGO_BRAND=mainline which is NOT accurate for meta-ti
which is distro independent, hence without appropriate changes while
using alternate distros, this change will not take effect.

+Subject: [PATCH] Revert "soc: am64x: Makefile: Move the SPL Load address to
+ 0x70000000"
+
+This reverts commit e411dc16862b5bb2d8befb12496b03d7b01c87b2.
+
+Mainline is NOT ready for the change yet as of u-boot 2021.07 + v5.13,
+So, this patch reverts the SPL address change.
+
+This patch needs to be dropped once mainline u-boot and kernel have
+migrated over to newer releases.
