+From df70c467c5d100f1522b4521f48da4c51e43688c Mon Sep 17 00:00:00 2001

+Date: Thu, 25 Aug 2022 13:48:22 +0000
+Subject: [PATCH 25/25] corstone1000: use a compressed kernel
+
+The corstone1000 kernel has become too large to fit in the available
+storage.  Swtiching to a compressed kernel avoids the problem, but
+requires uncompressing it.  Add this decompression to the default boot
+instructions.
