From 7a0d88076b9cd8ccc88d41383f92ac2494d4168e Mon Sep 17 00:00:00 2001 From: Nathan Barrett-Morrison Date: Wed, 2 Feb 2022 15:05:18 -0500 Subject: [PATCH] Add in the ability to load and boot an uncompressed kernel image during the Falcon Mode boot sequence. This is required for architectures which do not support compressed kernel images (i.e. ARM64). This is only used while not booting via FIT image.
